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’re looking into this area of interest there are many different professions that will be and are available. Because of the vast variety of existing opportunities, it will also accommodate a number of different degrees and different types of training. Your goal is to find which career path is the right fit for you.

Certain jobs in communications, community outreach, sales, marketing and business support are available in every renewable energy field. In addition, each field will need construction workers for building of the facilities, architects for the building design, mechanical and electrical engineers for research and development and technicians to maintain operations of the buildings. There are other jobs that will specifically target certain renewable energy technologies.

The wind industry uses meteorologists in their search to find areas with adequate wind conditions. Certain speeds of wind are vital to allow wind farms to generate enough electricity. In addition, advanced degree aeronautical engineers are needed for research and development in efforts to improve design and operations. Mechanical and electrical technicians, called “wind smiths” are needed to maintain the wind turbines.

The solar power industry has a need for highly skilled professionals. The different areas would consist of photovoltaics, solar thermal electric, solar hot water systems and passive solar building design. Higher-level jobs would include chemical, material science and physics engineers who would take the lead in research and development to improve solar products costs and reliability.

Much research is needed to make biomass energy production, the conversion of biomass into fuel, an easier process. This research effort will require the aid of chemists, microbiologists, biochemists, agricultural specialists and engineers. It will also create a number of direct and indirect jobs in rural communities. There will be an increase in jobs for farmers and foresters to produce and collect biomass resources. There will also be a need for more truck drivers to transport resources to the plants. There may even be a need for chemical engineers cross-trained in engineering and biology or chemistry and agriculture.

Geothermal energy production requires geologists, geochemists, geophysicists, hydrologists, seismologists, reservoir engineers, mud loggers, hydraulic engineers and drillers for the development and location of reservoirs. Environmental scientists will be needed for impact studies and for the obtainment of permits. HVAC contractors and drilling crews are also needed for manufacturing and installing geothermal heat pumps. Direct use of geothermal technology will have a need for heating engineers and those trained in building and agricultural industries. Electrical machinists, welders, riggers and mechanics are also needed in the design and construction processes.

Hydropower industry will employ recreation planners, resource managers and educators in managing the reservoirs and surrounding lands. The employment of environmental scientists such as, biologists, hydrologists, ecologists, and wildlife habitat specialists will be needed for conducting impact studies. They are needed to examine the effect hydropower has on the environment, to deal with environmental safety and to satisfy state and federal licensing laws.

The renewable energy field offers careers for individuals with a number of different skills, degrees and training. By being among those who will apply their talents and areas of expertise to any of the renewable energy fields, you can help the United States in its quest to provide an safe, environmentally friendly energy to its citizens.

An alternative energy resource, gaining much market share, is solar power. It is the one that is most well known every day. This involves the manufacturing of solar cells which gather and focus the sun’s energy, and translate it into electricity. In some, hot water can be produced from the sun. As with wind energy, solar energy creates absolutely zero pollution.

One of these renewable energy resources is solar energy. Solar PV cells continue to be manufactured that are often more energy efficient and less costly than previous models from a few years ago. Solar energy plants have been developed in in many nations. They are now more strategically placed in order to improve the national electricity grid. Over time, they are not causing environmental issues as previous placement of solar panels may have caused.

The following sections provide a summary overview of many other renewable energy sources being researched, developed, and deployed throughout the world.

Ocean current energy is discussed by governments and investors as having untapped energy generating potential. A ocean electricity generator in Europe has been in operation for a long time. It is thought to be a great accomplishment. The Irish and Scots are also running pilot facilities.

Hydroelectric power has been with us for a while. At current hydro dams, it is a clean generator of electricity. Because water and gravity is used, it is more effecient than a grid powered by natural gas. There are restrictions to the availability of the right places to set up a large dam. Many river based, or small and localized, hydro generators where created in recently due to this limitation.

Geothermal energy is extremely abundant. Since it lies directly beneath us, we only need drill just a few miles below the earth’s surface to find huge amounts of energy. This energy is produced by the heating of water, trapped in layers of rock, through the earth’s hot molten core. The water turns to steam, which is then used to drive turbines that generate electricity. Great amounts of research and development should be put into geothermal energy tapping.

Biodiesel energy is created out of the oils contained in plants. Most commonly, the retail stockpiles of bio-diesel have been created using rapeseed and sunflower oils. At the time of this writing, biodiesel is typically produced by agricultural corporations or those who want to experiment with renewable energy. Venture interest from companies across the World is on the rise. It burns much better than fossil fuel diesel.

Another renewable energy resource is solar generated electricity. Solar PV cells continue to be manufactured that are often more energy efficient and less costly than previous models from a few years ago. This involves the manufacturing of solar panels which gather and focus the sun’s energy, and translate it into electricity. In other cases, hot water can be produced from the sun. As with wind energy, solar energy creates absolutely zero pollution.

New Delhi, One of the most debated topics today is the future scenario of energy use. The focus is now on a range of technologies that are expected to emerge in the coming years and decades. There is universal recognition of the fact that new technologies and much greater use of some that already exist provide the most hopeful prospects for mitigation of emissions of gases that threatens our planet.

The good news, experts agree, is that renewable energy can deliver half of the world’s energy needs by 2050.Some reports show that it is economically feasible to cut global CO2 emissions by almost 50% within the next 43 years. They also agree that commercial production of renewable energy on large to massive scales is technically possible.

Alongside global warming, other challenges have become just as pressing. Worldwide energy demand is growing at a staggering rate. Over-reliance on energy imports from a few

countries and volatile oil and gas prices have together pushed security of energy supply to the top of the global energy-economy agenda.

Renewable energy is not a dream for the future – it is real, mature and can be deployed on a large scale. Decades of technological progress have seen renewable energy technologies such

as wind turbines, solar photovoltaic panels, biomass power plants and solar thermal collectors move steadily into the mainstream. The global market for renewable energy is growing dramatically; in 2006 its turnover was US$ 38 billion, 26% more than the previous year.

Supplies of all fossil fuels – oil, gas and coal – are becoming scarcer and more expensive to produce. Uranium, the fuel for nuclear power, is also a finite resource. By contrast, the reserves of renewable energy that are technically accessible globally are large enough to provide about six times more energy than the world currently consumes – forever.

Renewable energy technologies vary widely in their technical and economic maturity, but there are a range of sources which offer increasingly attractive options. These sources include wind, biomass, photovoltaic, solar thermal, geothermal, ocean and hydroelectric power. Their common feature is that they produce little or no greenhouse gases, and rely on virtually

inexhaustible natural sources for their “fuel”.

The forecast is that by 2050, 50% of primary energy demand in India will be covered by renewable energy sources.

In many countries today, a lot is being said about harnessing renewable energy technologies – particularly in light of the rising oil prices.

Renewable energy is power which has been generated from renewable resources – in other words, it does not “run out” or eventually become depleted. It can be continuously re-created.

It’s not just the prices of oil that has people searching for clean and renewable energy sources. Global warming concerns, and problems created by international pollution, have triggered this concern as well. Governments around the world have begun to support research on improving the renewable energy technologies.

Currently, the five common renewable energy sources are biomass, hydropower, geothermal heat, wind, and solar power.

Biomass

Biomass consists of organic material which has been produced by animals and plants. Biomass energy uses stored energy from the sun. This is a result of the natural process which any plant uses to survive – photosynthesis.

Because we can always grow new crops and trees, biomass is considered a form of renewable energy. Furthermore, organic waste can be used to create biomass as well.

Some examples of commonly used biomass fuels are crops, wood, garbage, and manure. When these materials are burned, they emit heat which produces steam, that can in turn be used to create electricity. Some biomasses are converted into other usable energy forms, such as methane gas or biodiesel.

Hydropower

Hydropower is one of the oldest forms of renewable energy. It was used in ancient times to grind grain. Coal was once the only source of power in the United States. But in 1880, the first Hydropower plant was built, and since then, more of these have been erected in order to provide the people with electricity.

Geothermal Energy

Geothermal Energy comes from within the Earth itself. The steam or heat which stems from the center of the earth can be used to regulate the temperatures of buildings, and can be used to generate electricity as well.
Because water can always be replenished by rain, and because the earth’s core maintains its temperature, this is considered one form of renewable energy.

Wind Power

Even the ever-present wind can provide a renewable energy source. Wind is created as a result of the uneven heating on the earth’s surface, which causes air to move. Thus, wind power is essentially a bi-product of solar power. Wind propellers are used to collect the wind’s kinetic energy, which turns turbines that are in turn used to create electricity.

Solar Power

This form of renewable energy will be available as long as the sun shines. Solar energy can either be used as thermal energy, or it can be converted into electricity.

As a thermal energy, it can be used to heat water or spaces. Through the use of solar cells or similar photovoltaic devices, it can be used to create electricity. The heat of the sun can also be used to create steam, which turns turbines and thus produces electricity.
