The worldwide supply of fossil fuels is very much less now than it was pre-1970. With this in mind, environmentalists, governments and the media itself are in agreement that something must be done as the demand keeps rising. More people are taking a closer look how to use the information on renewable energy in their lives.

One of the major problems concerning the use of fossil fuels is the impact them are having on the environment. If you take a look at the use of fossil fuel and global warming, you will find a straightforward correlation between the two. The impact that global warming has on the weather cycles like extra hot summers, and warmer than regular winters, or more severe storms in general can forcefully affect the way of life of humans and animals alike.

Take the time to head to the library or video store and get a copy of ‘An Inconvenient Truth’ an educational documentary that will explain the damage of global warming in today’s world. You will find yourself choosing to make some changes to your home to make it more energy efficient, or look for other ways to bring renewable energy into the design of a new home or remodeling project, just from what you find out in the movie.

A major point in the information on renewable energy is that is what they call “green and clean” energy, thus producing a minimal carbon footprint. Because of this many, people are getting on the renewable bandwagon and choosing to use such renewable energy sources as solar power, wind power and geothermal energy. In addition, this boom of interest will naturally result in more well paying jobs being created in the renewable energy industry that will stay in the United States.

Add the government to the list of sources of renewable energy with their incentives and tax credits for those installing energy efficient technology in their homes. If you install solar power devices in your home, you can presently qualify for federal tax credits. The tax credits apply to both commercial and residential properties and the bottom line can mean the cost will end up being about 30% discount.

By making renewable energy more affordable and within their reach, people tend to be more willing to install renewable energy technology to help protect the environment from further global warming. Those people who choose to install renewable energy are often those same people that promote green communities.

Many of these communities work hard to provide information on renewable energu to its environmentally conscious citizens, so they can do what they can to improve the environment and the world that they live in. A green city can make environmental policies for the people to use to cut down on damaging pollution and create energy efficient citizens. Every year, National Geographic produces the Green Guide. It gives great information about a number of green issues and also lists the Top 10 Green Cities. Is your city going to be featured in this year’s guide?

Plenty of books have been written that give information on renewable energy. To be fair, we really should mention something about renewable energy disadvantages. Hands down, the disadvantage that sticks out like a sore thumb continues to be the high sticker price of purchasing and installing renewable energy technology in your home. Average folks will never be able to afford the $20,000 cost to install a PV solar system until the cost comes down or if they happen to have disposable cash available to them. Some will be looking to build-it-yourself options for renewable energy technology.

There are many energy sources today that are extremely limited in supply. Some of these sources include oil, natural gas, and coal. It is a matter of time before they will be exhausted.

Estimates are that they can only meet our energy demands for another fifty to seventy years. So in an effort to find alternative forms of energy, the world has turned to renewable energy sources as the solution. There are many advantages and disadvantages to this.

Renewable energy sources consist of solar, hydro, wind, geothermal, ocean and biomass. The most common advantage of each is that they are renewable and cannot be depleted. They are a clean energy, as they don’t pollute the air, and they don’t contribute to global warming or greenhouse effects. Since their sources are natural the cost of operations is reduced and they also require less maintenance on their plants. A common disadvantage to all is that it is difficult to produce the large quantities of electricity their counterpart the fossil fuels are able to. Since they are also new technologies, the cost of initiating them is high.

Solar energy makes use of the sun’s energy. It is advantageous because the systems can fit into existing buildings and it does not affect land use. But since the area of the collectors is large, more materials are required. Solar radiation is also controlled by geography. And it is limited to daytime hours and non-cloudy days.

Wind energy uses the power of the wind to produce electricity. Although it is the largest job producer, it is reliant on strong winds. Wind turbines are large and, although you can use the area under them for farming, many consider them unattractive looking. They are also very noisy to operate. In addition, they threaten the wild bird population.

Hydroelectric energy uses water to produce power. This is the most reliable of all the renewable energy sources. On the down side, it affects ecology and causes downstream problems. The decay of vegetation along the riverbed can cause the buildup of methane. Methane is a contributing gas to greenhouse effect. Dams can also alter the natural river flow and affect wildlife. Colder, oxygen poor water can be released into the river, killing fish. And the release of water from the dam can cause flooding.

Geothermal energy uses steam from the Earth’s ground to generate power. It uses smaller land areas than other power plants. They can run 24 hours per day, every day of the year. Disadvantages are that it is very site specific and, along with the heat from the Earth, it can also bring up toxic chemicals when obtaining the steam. Drilling geothermal reservoirs and finding them can be an expensive task.

Biomass electricity is produced through the energies from wood, agricultural and municipal waste. It helps save on landfill waste but transportation can be expensive and ecological diversity of land may be affected. In addition, its process needs to be made simpler.

Ocean energy is a clean and abundant energy form. It does, however, have high costs. Ocean thermal energy also requires close to a forty degree Fahrenheit difference in water temperature year round. In addition, construction and laying pipes can cause damage to the ecosystem.

There are many advantages to the use of renewable energy sources. There are also some disadvantages. The fact is energy demands will continue to increase. Through research and development, as well as, new technologies, the hope is many of the disadvantages of renewable sources of energy can be eliminated and we can successfully incorporate it into our power supplies.

You think you understand renewable energy credits. You’re sure you understand Carbon Offsets. You are fuzzy on the details about how they differ and when the purchase of one or the other might be appropriate. Never fear! This article explains the key differences, and similarities, between the two.

The first difference is the way that offsets and Renewable Energy Credits (RECs) are measured. Carbon offsets are measured in metric tons of C02 or C02 Equivalent. Renewable Energy Credits are measured in kilowatt hours, which are a standard electricity measurement metric. A kilowatt hour is the amount of work that can be performed by one kilowatt of energy in one hour.

Picture a lonely, dim lightbulb hanging from the ceiling that turns on for one hour each day by which you feverishly darn socks in a carbon constrained world; that’s a watt, and for the privilege of its use, you’ll be charged for 1/1000 kwh of electricity each day. These days, you probably use a several kwh per day.

The second difference between carbon offsets and renewable energy credits is that renewable energy credits only come from renewable energy projects (solar, wind geothermal, biofuels, etc.) while carbon offsets can come from all different kinds of projects, including renewable energy generation, that reduce the level of greenhouse gases that are entering the atmosphere.

To put it another way, RECs are primarily concerned with promoting the generation of clean energy, while carbon offsets are primarily concerned with preventing the emissions that enter the atmosphere.

They are both systems that have developed to deal with global warming systematically, but they have different approaches. RECs are forward looking, focused on building a clean energy economy and providing an extra incentive for the creation of renewable energy, while carbon offsets are oriented in the present, dealing with preventing greenhouse gases from entering the atmosphere right now.

Because of these different measurement systems and the different foci of the two programs, RECs and carbon offsets have different precision rates when it comes to carbon. Carbon offsets are all about exactitude, and many of the discussions about the efficacy of offsets center around the degree of certainty a buyer has that the exact amount of carbon s/he has paid for is actually being prevented or captured. RECs, on the other hand, are measured in kilowatt hours, and the carbon content of that ‘saved’ kwh differs depending on the location of the project and the quality of the local electricity.

The dirtier the local electricity, the more carbon an REC ‘saves.’ Different utilities around the country use different mixes of energy sources, from coal to natural gas to renewables, to create electricity. These sources vary widely in their carbon content. To make matters even more confusing, a utility might even change the mix it uses depending on the time of day- when peak load sets in they might have to rely on dirtier power sources than they would otherwise.

So, it’s impossible to say exactly how much carbon a clean kwh of renewable energy ‘offsets.’ The closest we can get is to use the ‘emissions factor’ for energy from the local utility, which is the average emissions for the mix of sources that the utility uses to create power, and multiply it by the number of kilowatt hours to produce an estimate of the carbon saved per kilowatt. But it will always be an estimate.

This is not to say that RECs are no good. They are an extremely effective way to promote clean energy because they give the providers and extra incentive to keep creating clean energy and we need all the incentives we can get to move toward a clean energy economy. RECs just aren’t the most accurate way to offset carbon. I highly recommend using RECs to offset electricity use, because your electric bills will have a record of the exact number of kwh you used, and you can buy RECs to account for all the dirty emissions your plugged-in Macbook caused. Then, you can buy carbon offsets to cover all your driving and flying.

‘But what about renewable carbon offsets?’, you say. ‘Those seem like the best of both worlds!’ I’m getting there. Those are good to, and if you really value the promotion of clean energy despite some of the accuracy issues, you can buy renewable energy offsets. Many times offsets will actually come from the exact same projects as the RECs, but the nice thing about buying the offset version instead of buying RECs and doing the calculations yourself is that someone else, hopefully a third party verifier, is determining how much carbon each kwh of clean energy replaced. So you don’t have to! Rest easy, and lay off the carbon guilt.

To many people, the differences between “alternative energy,” “renewable energy,” and “clean energy,” might not be obvious. But each term is unique and has its own individual definition. These three terms are not all exactly the same.

Alternative Energy

When we speak of alternative energy, we refer to sources of usable energy that can replace conventional energy sources (usually, without undesirable side effects). The term “alternative energy” is typically used to refer to sources of energy other than nuclear energy or fossil fuels.

Throughout the course of history, “alternative energy” has referred to different things. There was a time when nuclear energy was considered an alternative to conventional energy, and was therefore called “alternative energy.” But times have changed.

These days, a form of “alternative energy” might also be renewable energy, or clean energy, or both. The terms are often interchangeable, but definitely not the same.

Renewable Energy

Renewable energy is any type of energy which comes from renewable natural resources, such as wind, rain, sunlight, geothermal heat, and tides. It is referred to as “renewable” because it doesn’t run out. You can always get more of it.

People have begun to turn to this type of energy due to the rising oil prices, and the prospect that we might one day deplete available sources of fossil fuels, as well as due to concerns about the adverse effects that our conventional energy sources have on the environment.

Of all the different types of renewable energy, wind power is one which is growing in its use. The number of users who have some form of wind power installed has increased, with the current worldwide capacity being about 100 GW.

Clean Energy

“Clean energy” is simply any form of energy which is created with clean, harmless, and non-polluting methods.

Most renewable energy sources are also clean energy sources. But not all.

One such example is geothermal power. It may be a renewable energy source, but some geothermal energy processes can be harmful to the environment. Therefore, this is not always a clean energy. However there are also other forms of geothermal energy which are harmless and clean.

Clean energy makes the less impact on the environment than our current conventional energy sources do. It creates an insignificant amount of carbon dioxide, and its use can reduce the speed of global warming – or global pollution.

As you can see, alternative energy, renewable energy, and clean energy are very similar. But it is important to know that there are differences.

There are many actions which can be taken, to help reduce the greenhouse gases in our atmosphere. Some of these steps can be taken in your own home. Many clean energy solutions can can be easily installed, and some kits are quite affordable.

Carbon emissions and other forms of pollution are not only created by heavy industrial factories. They are created in the common household as well. Energy efficiency has become an important aspect of our lives.

It’s important to start making changes now; if we want to save our planet for our children, for the flora and fauna of the Earth, and for the future of mankind. Clean energy, to be exact, can make a big difference.

Renewable energy has its uses but they aren’t all advantageous. In this piece some of the benefits and adverse effects of renewable energy are considered and examined in different forms of renewable energy.

When people think or energy sources, they mostly think of coal, natural gas and oil, these fuels have been the source of energy for a number of years. However one problem is that they are limited in supply and availability.

Estimates have shown that the currently available sources will only meet our current energy demands for about 50 to 70 years or so. In order to find alternative sources of energy the world has decided to pursue renewable energy sources. However even renewable energy sources have their advantages and disadvantages too.

The available renewable energy sources that we have include solar, hydro, wind, geothermal, ocean and biomass. The most common of these advantages is that they are clean energy sources and do not pollute the air. They also do not contribute to global warming or greenhouse effects. Because the sources of such energy are natural the cost of operations are substantially reduced and they require less maintenance on their plants. One common disadvantage is that it is impossible to produce large quantities of electricity than can be done with fossil fuels. Because they are new technologies the costs of initiating them is also high.

Solar energy utilizes the energy from the sun. It has its advantages because these systems can easily fit into existing buildings and do not affect land use. Since the area that these collectors rest in is quite large, a lot more materials are needed. Solar radiation is also controlled by geography too. It is also limited to the daytime as well as non-cloudy days.

Wind energy makes use of the power of the wind in order to create electricity. Though it produces the most jobs it is reliant on strong winds too. Wind turbines tend to be large and though the areas under them can be used for farming, most people think of them as unattractive looking. These turbines are also very noisy to operate and they threaten the population of wild birds too.

Hydroelectric energy makes use of water in order to produce power. It is the most reliable of all energy sources that are renewable. Its disadvantages are that it affects the ecology and causes downstream problems. Decay of vegetation on the riverbed can also cause a buildup of methane which contributes to the greenhouse effects. Dams may also cause an alteration of the natural river flow and affect wildlife in the area as well. Water which is colder and which is lacking in oxygen tends to be released into the water this kills the fish, sudden release of water like this may also result in flooding.

Geothermal energy makes use of the steam from the Earth’s ground in order to generate power. It uses a smaller land area that other types of power plants. They can literally run continuously throughout the year. The disadvantages tend to be that these plants are site specific and it can bring up toxic chemicals and heat from the earth when it tries to obtain the steam. Drilling such geothermal reservoirs can also cost a lot.

Biomass electricity is made from the energies of wood, agricultural and municipal waste. It tends to help save on landfill waste but the transportation is also expensive and tends to affect the diversity of the land. Other than this the process is quite complex and should be much simpler.

Ocean energy is a clean and abundant energy form. It tends to be expensive and in order to access this energy, you need at least a 40 degree Fahrenheit difference in water temperature throughout the year. Other than this, the construction and putting in place of pipes may damage the ecosystem.
