Renewable Energy Cannot Sustain a Consumer Society

What Are The Types Of Renewable Energy?

What is Renewable Energy?

Renewable energy uses energy sources that are continually replenished by nature—the sun, the wind, water, the Earth’s heat, and plants. Renewable energy technologies turn these fuels into usable forms of energy—most often electricity, but also heat, chemicals, or mechanical power.

Why Use Renewable Energy?

Today we primarily use fossil fuels to heat and power our homes and fuel our cars. It’s convenient to use coal, oil, and natural gas for meeting our energy needs, but we have a limited supply of these fuels on the Earth. We’re using them much more rapidly than they are being created. Eventually, they will run out.

And because of safety concerns and waste disposal problems, the United States will retire much of its nuclear capacity by 2020. In the meantime, the nation’s energy needs are expected to grow by 33 percent during the next 20 years. Renewable energy can help fill the gap.

Even if we had an unlimited supply of fossil fuels, using renewable energy is better for the environment. We often call renewable energy technologies “clean” or “green” because they produce few if any pollutants. Burning fossil fuels, however, sends greenhouse gases into the atmosphere, trapping the sun’s heat and contributing to global warming. Climate scientists generally agree that the Earth’s average temperature has risen in the past century. If this trend continues, sea levels will rise, and scientists predict that floods,

heat waves, droughts, and other extreme weather conditions could occur more often.

Other pollutants are released into the air, soil, and water when fossil fuels are burned. These pollutants take a dramatic toll on the environment—and on humans. Air pollution contributes to diseases like asthma. Acid rain from sulfur dioxide and nitrogen oxides harms plants and fish. Nitrogen oxides also

contribute to smog.

Renewable energy will also help us develop energy independence and security. The United States imports more than 50 percent of its oil, up from 34 percent in 1973. Replacing some of our petroleum with fuels made from plant matter, for example, could save money and strengthen our energy security.

Renewable energy is plentiful, and the technologies are improving all the time. There are many ways to use renewable energy. Most of us already use renewable energy in our daily lives.

Bioenergy

Bioenergy is the energy derived from biomass (organic matter), such as plants. If you’ve ever burned wood in a fireplace or campfire, you’ve used bioenergy. But we don’t get all of our biomass resources directly from trees or other plants. Many industries, such as those involved in construction or the processing of agricultural products, can create large quantities of unused or residual biomass, which can serve as a bioenergy source.

Biofuels

Biomass can be converted directly into liquid fuels, called biofuels. Because biofuels are easy to transport and possess high energy density, they are favored to fuel vehicles and sometimes stationary power generation. The most common biofuel is ethanol, an alcohol made from the fermentation

of biomass high in carbohydrates.

The current largest source of ethanol is corn. Some cities use ethanol as a gasoline additive to help meet air quality standards for amounts to 50,000 times the energy of all oil and gas resources in the world. In the United States, most geothermal reservoirs are located in the western states, Alaska, and Hawaii. GHPs, however, can be used almost anywhere.

Biobased Products

Biomass—corn, wheat, soybeans, wood, and residues—can also be used to produce chemicals and materials that we normally obtain from petroleum. Industry has already begun to use cornstarch to produce commodity plastics, such as shrinkwrap, plastic eating utensils, and even car bumpers.

Commercial development is underway to make thermoset plastics, like electrical switch plate covers, from wood residues.

Geothermal Energy

The Earth’s core, 4,000 miles below the surface, can reach temperatures of 9000° F.

This heat—geothermal energy—flows outward from the core, heating the surrounding area, which can form underground reservoirs of hot water and steam. These reservoirs can be tapped for a variety of uses, such as to generate electricity or heat buildings. By using geothermal heat pumps (GHPs), we can even take advantage of the shallow ground’s stable temperature for heating and cooling buildings.

Solar Energy

Solar technologies tap directly into the infinite power of the sun and use that energy to produce heat, light, and power.

Wind Energy

For hundreds of years, people have used windmills to harness the wind’s energy. Today’s wind turbines, which operate differently from windmills, are a much more efficient technology.

Wind turbine technology may look simple: the wind spins turbine blades around a central hub; the hub is connected to a shaft, which powers a generator to make electricity.

However, turbines are highly sophisticated power systems that capture the wind’s energy by means of new blade designs or airfoils. Modern, mechanical drive systems, combined with advanced generators, convert that energy into electricity.

Ocean Energy

The ocean can produce two types of energy: thermal energy from the sun’s heat, and mechanical energy from the tides and waves.

Ocean thermal energy can be used for many applications, including electricity generation. Electricity conversion systems use either the warm surface water or boil the seawater to turn a turbine, which activates a generator.

Hydrogen

Hydrogen is high in energy, yet its use as a fuel produces water as the only emission. Hydrogen is the universe’s most abundant element and also its simplest. A hydrogen atom consists of only one proton and one electron.

Despite its abundance and simplicity, it doesn’t occur naturally as a gas on the Earth.

If you have, in no way, reflected on renewable energy, this may be an excellent occasion to learn it by heart. There are a lot of paybacks to generate renewable energy. Therefore, if you want to know more about renewable energy, it is best that you hire a Renewable Energy Specialist. This will walk you through the proper ways of dealing with all matters and details in connection with renewable energy.

Renewable energy is energy produced through nature like, wind, sunbeams, rainwater, and geothermal heat and wave, which can be renewed. Almost all renewable energy ventures is on a gigantic-scale, renewable technologies are also appropriate to small off-grid task, at times in rural and out-of-the-way parts, where energy customarily has a very important part to play in human wellbeing and interests.

The superior fraction of invigorated energy is given by the sun in the form of solar energy which facilitates the development of plants and the carrying out of hydroelectric ventures. Wind energy can be in use to run wind turbines and does not manufacture greenhouse gases. The energy in water is also recognized as hydroelectricity and may take the form of kinetic energy. This can also be utilized and harnessed. The energy sources energy are of renewable energy are biofuel, liquid biofuel, biogas, solid biogas and geothermal. You can better know all of these by means of hiring a very proficient and professional Renewable Energy Specialist.

Any ordinary man will also be in admiration as he meets the informations that he can receive as paybacks by using renewable energy. This must be explained further by yourRenewable Energy Specialist so that you will be well aware of what you can get from this amazing energy source. Some of the benefits are the following:

•    A great decrease in your electrical bill. When you begin to observe alternate sources of energy, you can cut back on your monthly utility bill, and possibly get rid of it.
•    Renewable Energy does not come at an ecological expenditure. It comes from resources that will never come to an end, such as sun and the wind.
•    There are no damaging releases from green source of energy.
•    No noise connected with its generation.
•    This does not engage the expenditure of fossil fuels.

The employment of fossil fuels creates countries susceptible to political arguments, in addition to being reliant upon foreign sources. By having Renewable Energy Specialist who can best handle the alternate sources of energy, we can do away with this dependence.

So, think about the reimbursement of switching over to a renewable energy source with the help of Renewable Energy Specialist. There is no superior time than at this very moment to come across with a wide-ranging step by step guide for structuring your own solar panels or wind turbines with the assistance of Renewable Energy Specialist. Loads of of these guides are instantaneously downloadable; they do not cost a great deal and are trouble-free for any person to put into practice.

Considering the current state of the economy, it is no surprise that a significant amount of people are doing everything they can to cut costs and to save money. Traditional cost cutting methods include downsizing vehicles, cutting out vacations, buying cheaper food, eating out less and so forth. However, a growing number of people are turning to alternative and renewable energy to save money.

Advances in technology have made renewable energy sources such as solar and wind power much more efficient, affordable and viable for the average person. In some cases, people take using renewable energy to provide the electricity to their homes to the next step, disconnecting from their local electrical service and going entirely off the grid.

Living off the grid is not a step to be taken impulsively or rashly, but rather one to be well thought out and planned for. If one lives in the country and has the space and ability to install a very large wind generator, then going off the grid on wind power could work. However, living off the grid on solar power is a much more realistic and safe route to take. Modern solar panels are very efficient and can now provide significant amounts of power even on a cloudy day.

Living off the grid on solar power is possible with discipline and the correct preparation. Converting to a tankless hot water heater is an important preparation to going off the grid. Heating water with an electric or even a gas hot water heater is very expensive. Tankless heaters are dramatically more efficient and reduce the electric load. Another important preparation for living off the grid is to get set up to dry clothes on a clothes line to avoid using the clothes dryer. The dryer uses a huge amount of electricity to get the clothes dry. This is easy to do outdoors in the summer, and there are many types of drying wracks available to dry the clothes on indoors in the winter.

Yet another preparation to living off the grid is to replace all the light bulbs in the house with energy efficient fluorescent bulbs. Lastly, one should make every effort to make the house airtight, so heat and cold are retained and do not leak out or in the house due to old inefficient window, unsealed doors, and improperly insulated walls. Make sure there is good weather stripping around all doors and windows and make sure there is an efficient programable thermostat installed.

Living off the grid with solar power is certainly possible, but it requires some important preparations to make sure that the house is as energy efficient as possible since there is no backup source of power once the solar cells have been depleted between charges. The preparation and installation of the system can be expensive initially, but living off the grid saves so much money in electrical bills that these costs are often recovered withing the first two years of being off the grid.

The environmental movement and the general feeling toward environmental responsibility has been gradually increasing for the past 10 years and has increased dramatically in just that past 4 years. Renewable energy, pollution control, environmental responsibility are all becoming mainstream concepts and goals.

As people become more conscious of the environment and are motivated to save money by using renewable energy by the ailing economy, a new type of lifestyle seems to be emerging; living green. The term “green” is now a mainstream term that indicates environmentally responsible or pollution free, or energy efficient.

Living green or “being green” has become such a high profile issue, that it has actually become a defined lifestyle that for many people living it, feels very good on a number of different levels. Someone who is living green:

Usually spends much less money on utilities, food, and fuel. Being green usually means that one drives a hybrid vehicle, or at least a vehicle that gets superior gas mileage. They don’t spend as much money on gas.

Being green means that one most likely has a renewable energy system in their household such as solar or wind power that saves them an amazing amount of money in electric bills.

Being green feels good because they tend to eat healthier than the average person. Many people living the green lifestyle ear many all natural and organic foods that contain no toxins, preservatives and have little or no saturated fat content. These people are eating significantly healthier than the average person, and in many cases are spending less money on their foods.

The green lifestyle has an emphasis on exercise and outdoor activity. Many people being green have gardens in which they grow their own organic or all natural vegetables to eat. This not only saves money but is a good past time that provides exercise.

In short, being green feels good for health, financial, and social reasons. The green lifestyle is inherently connected to health and well being, so people living green will exercise more and eat healthier. Being green usually means that ones household is as energy efficient as possible, which by definition means that they are saving a ton of money in utility bills.

Being green is a lifestyle choice that has a positive impact on the general environment, which helps give many people a positive sense of purpose that sustains them and gives their lives added meaning. As the economy has grown worse, many people have adopted the green lifestyle out of desperation to save money and to become more efficient.

Many people will pick up the principles of being green for purely financial reasons and will then become enamored with the entire lifestyle and will adopt the idealism of the entire green movement in general. Being green is becoming a powerful force for change in this country, on a social, financial and environmental level. As more and more people adopt the living green lifestyle, the economy and the environment will gradually improve.

If you have ever wanted to save money on your energy bill by converting to other renewable energy systems, then you have come to the right place.  Did you know that you can easily convert your home into a solar energy power plant and completely reduce or eliminate your power bill?  Well you can and it is very easy to do and extremely affordable.  You do not need to spend thousands of dollars to do this, like some would have you believe.  You can actually transform your home with less than 200 dollars using a simple do it yourself kit.  You do not need any previous experience setting up power systems and you do not need any technical knowledge whatsoever.  You can begin with simple tools from your home and begin generating electricity that will last you the rest of your life.

You will never have to pay a power bill again.  You can also become eligible for rebates from your power company by using renewable energy systems too.  Many people today just cannot cope with the rising costs of energy and that is why right now has never been a better time to look at alternative energy resources.  In the future, most homes will be equipped with solar and wind powered energy systems.  These people however, will have to pay an arm and a leg to be able to generate power because they will not know of the simple way that they can set up their own system.  In the future, there will be an industry geared towards generating these types of energies, but not for a long time to come.  In the future, you may not be able to save as much money as you can by doing this yourself today, because of the fact that it will be monopolized.  No one knows exactly when this will occur, as we are so dependant on conventional types of energy systems today, that is why the best time is now to look into developing your own renewable energy system.

For complete information on how to set up your own system, you will have to get a do it yourself kit, video and manual.  They are sold widely on the internet.  This is the best way to get information on how to develop renewable energy for yourself and others.  With the purchase of your own manual for setting up a renewable energy system, you could be saving yourself, and others thousands and thousands of dollars in energy costs.

As a homeowner, you may be using renewable energy sources. Let’s look at a few of these important, powerful sources.

If you use solar powered lights to brighten your walkway, a solar cover on your swimming pool or hang your clothes out to dry, you are already making use of the sun’s renewable energy. There are many other renewable energy home options you can take advantage of, and by doing so, help preserve our environment.

The most practical of renewable energy options for the home consist of space heating and domestic hot water. This is over 50% of a household’s energy usage. In using renewable energy we can experience cost saving benefits.

Perhaps the best way to take advantage of renewable energy home options is when designing a new house. A southern wall taking advantage of an appropriate amount of windows can take full use of the low sun in the winter. Adding a roof overhang over these windows allow the higher summer sun to be blocked. Also, on a cool day you can open your windows to let a breeze cool off the house and make use of wind energy. You have achieved adding heat in the winter and coolness in the summer, thereby lowering your heating and cooling costs naturally. This is called passive solar heating since it is integrated with no extra costs. You can also do day lighting by taking full advantage of the sunlight during the day to take care of your daytime lighting needs.

Wood stoves can also be advantageous, if using only dead wood, diseased wood or small pellets made from wood chips, crop waste and other organic material for burning. This is a renewable source of heat through the use of space heating. Modern wood burning stoves are highly efficient, making it a more practical option.

A homeowner can also utilize active solar heating. A solar water heater can use renewable solar energy to heat water for a house. This would use solar collector panels placed on a roof. Water runs through pipes under these panels and is heated by the sun. The water travels to a water tank in your home for your use. Electricity can also be produced for a home using the photovoltaic technology. This runs on the same idea as a solar calculator. Solar electricity is ideal for rural homes where it would be difficult to run an electric line to.

Geothermal heat pumps use the heat from the Earth to move heat from one area to another. This system uses a series of underground pipes to move a heat exchange fluid. The heat pump moves this fluid, heated from the earth and transfers it to buildings for use. Initial installation costs are much the same as traditional heating systems, but operational costs are lower.

If you live in a windy part of the country and have quite a bit of land, wind can power a wind turbine to produce electricity for your household. But your location must be ideal to catch wind and you must be able to capture a certain amount for this to work.

These are some home options for renewable energy sources. By trying to utilize some of them we are preparing for our future by using clean energy that does not affect air quality or harm the environment.

Today, our lives, our societies and our planet are inextricably bound to what we are able to do about the worsening climate. Fortunately, more people are aware of the environmental issues and are motivated to take an active role in doing anything they can to reduce and eliminate their personal and household’s impact on the planet.

There a great number of people who are ideologically motivated to do everything that they can to avoid pollution and to use renewable energy, and there is also a growing number of people who are simply average citizens who are motivated to use renewable energy sources because it saves them money. Regardless if the motivation is idealistic or economic, the benefits of renewable energy are undeniable.

As our society evolves, our understanding of how our everyday actions can impart the planet also evolves. Today, more than ever, we are getting a realistic look at what will happen to our planet if we do not commit to an organized reform of how we obtain and use energy. There is a lengthy list of renewable energy benefits that can have a positive impact on a number of different social, economic and political levels. Some of the most noteworthy benefits of using renewable energy are:

Reduction of carbon and hydro carbon emissions produced from burning traditional fossil fuels to power vehicles, trains, planes, boats, homes and businesses
Reduced environmental impact by eliminating mining and drilling pollution
Healthier overall economy with the new jobs provided by the new industries necessary to produce and support renewable energy technology
A healthier population with the reduction in pollutants caused by burning fossil fuels
A stronger national security position with a reduction in dependance on foreign oil
A reduction in the ground water pollution caused by coal mining
A reduction in third world conflict as the focus shifts away from the control of oil
An improvement in impoverished third world nations as new opportunities arise in the untapped renewable energy industry
A healthier overall economy as people are able to save significant amounts of money in their heating and cooling bills by using solar and wind power

This last benefit listed is one of the most significant, because it deals with an issue that has immediate impact on a huge segment of the population. With advances in solar and wind generation technologies, it is now possible for the average middle class family to afford to install a solar or wind generation system in their home and to realize a dramatic savings in their utility bills. This savings helps the overall economy, since the money that is saved ultimately ends up helping the family avoid foreclosure, and otherwise ends up back in the economy.

Renewable energy has countless positive consequence and influences at multiple economic and social levels. From helping a struggling family cut costs, to reducing pollution to stimulating the economy by opening up new business opportunities in an untapped industry, renewable energy has benefits that can positively affect the lives of everyone on the planet.

Many parents want to teach their children about renewable energy and energy efficiency early in life because once they get in the habit of it, it will be a habit they continue to follow for the rest of their life. But where should you start when teaching renewable energy for kids?

A good start would be defining exactly what renewable energy is. You can suggest they make a list of non-renewable and renewable power sources and build from there. Some examples would be:

Non-Renewable: Oil/Gas, Natural Gas, Coal, Nuclear

Renewable: Solar, Wind, Geothermal, Hydro/Water

Explain to them how renewable energy comes from natural forces. It is different from fossil fuels as it does not make greenhouse gases or other pollutants.

You can further explain how the mass production of electricity using renewable energy sources has only recently become more popular. Some of the reasons why it’s becoming more popular include: climate change caused by pollution and fossil fuels are all being used up and becoming more expensive.

A great idea is to teach kids about energy efficiency. Have them make a list of all the powered devices they use for a day such as TV, computer, lights, etc. and for how long, and if possible the wattage of each device. If they can’t get the wattage, you can look up the average wattage for each device for demostration purposes. Do a rough calcuation to show them how much power they’re using in a day.

Now have them do an ‘energy conservation’ day where they turn off devices when they’re not using them, turn off lights when not in a room, turn down the heat/AC a couple degrees, etc. Now recalculate the daily wattage and show them how much energy they saved with a few simple changes.

Another great idea is show them how installing a solar panel or windmill can generate electricy for their own home. It’s not as expensive as you might think. You don’t need an expensive commerical system. You can build your own for $100-200 dollars and your kids could even help if they’re old enough. The less they take energy for granted, the better.

These lessons will stick with them (especially at such an impressionable age) and they’ll be using these practices for the rest of their life. Teach renewable energy for kids, the sooner the better!

Have you ever experienced power outages where you live? If you have you must know what a terrible experience that is. If you working on your computer and you haven’t saved your hard work you feel like the world is against you when the power dies. You will have no choice but to start over again if you can remember all the hard work you put in. If the power outages last longer that can be a disaster for the food in your fridge. If the power doesn’t come up soon you can start throwing food away. All and all the power outages can cause painful problems.

There is a simple solution for power outages and it can be found in renewable energy system. These renewable energy systems are suitable for home owners just like you and me not only for businesses. So, what are the advantages of using renewable energy as the primary source in our energy needs as an individual homeowner? There are several ways to profit from renewable energy.

Flexibility for specific needs

When you decide to purchase a total system solution you should consult a trustworthy business that specializes in renewable energy. When consulting these businesses they can design a total system that is suitable for your specific needs. If you have a home based business you probable have different energy needs then if you have regular job outside your home.
There are different systems to choose from. Be sure to consult a trustworthy business that can really offer you a good service and has been on business for several years. Almost every country or state in the US has specific tax reduction to profit from. These rules differ from country to country and state to state. You will to do a proper research or consult a professional to really profit from a renewable energy system.

Cutting Cost

With the use of renewable energy you can cut your cost dramatically. Of course you need to make sure that you use a system that is suitable for your needs. If you live in a sunny state than go solar, if you live in a windy state go with wind energy. If possible combine the different energy sources for an optimal solution.
You have to realize that the electricity charges are based on the prices of imported crude oil which are the primary fuel of our power plants. Once its prices soar high, expect that generation charges in your electric bill will increase. It is an advantage that you will just spend for an independent renewable energy system and its low monthly maintenance cost and the rest is history.

Availability and Abundance

A major advantage of renewable energy is that it is abundant and available in our environment. The state of Colorado in the US has a climate that is perfect in utilizing solar power by the use of photovoltaic panels complemented with wind generators. If your residence is situated in an area where there is good running water, you can install your own micro-hydro power system which can provide you reliable source of energy around the clock. As you can see there are enough possibilities to choose from.

In addition, these renewable energies are abundant in nature. As long as the sun is shining, the wind is blowing and the water in the river is flowing, expect that you can have unlimited supply of energy.

Above are just a few advantages listed for renewable energy listed. Of course renewable energy is also very environmental friendly. Investing in renewable energy is not only about saving money it is more about making this world a better place to live in for years to come.
