Natural energy sources -

Wind speed changes constantly, depending on the time of day, weather , and geographic location. Currently, it cannot be used to provide electricity for all our power needs.

Wind turbines can also be dangerous for bats and birds. These animals cannot always judge how fast the blades are moving and crash into them. The center of Earth is extremely hot—thought to be over 6, °C about 10, °F.

The heat is constantly moving toward the surface. Geothermal energy can melt underground rocks into magma and cause the magma to bubble to the surface as lava.

Geothermal energy can also heat underground sources of water and force it to spew out from the surface. This stream of water is called a geyser. We can access underground geothermal heat in different ways.

The water is warmed by the geothermal energy underground and brings the warmth aboveground to the building. Geothermal heat pumps can be used to heat houses, sidewalks, and even parking lots. Another way to use geothermal energy is with steam.

In some areas of the world, there is underground steam that naturally rises to the surface. The steam can be piped straight to a power plant. However, in other parts of the world, the ground is dry.

Water must be injected underground to create steam. When the steam comes to the surface, it is used to turn a generator and create electricity. In Iceland, there are large reservoirs of underground water. Almost 90 percent of people in Iceland use geothermal as an energy source to heat their homes and businesses.

Advantages and Disadvantages An advantage of geothermal energy is that it is clean. It does not require any fuel or emit any harmful pollutants into the air. Geothermal energy is only avaiable in certain parts of the world. Another disadvantage of using geothermal energy is that in areas of the world where there is only dry heat underground, large quantities of freshwater are used to make steam.

There may not be a lot of freshwater. People need water for drinking, cooking, and bathing. Biomass Energy.

Biomass is any material that comes from plants or microorganisms that were recently living. Plants create energy from the sun through photosynthesis.

This energy is stored in the plants even after they die. Trees, branches, scraps of bark, and recycled paper are common sources of biomass energy. Manure, garbage, and crops , such as corn, soy, and sugar cane, can also be used as biomass feedstocks.

We get energy from biomass by burning it. They can be stored and burned to create heat or generate electricity. Biomass can also be converted into biofuel.

Biofuels are mixed with regular gasoline and can be used to power cars and trucks. Biofuels release less harmful pollutants than pure gasoline. Advantages and Disadvantages A major advantage of biomass is that it can be stored and then used when it is needed.

Growing crops for biofuels, however, requires large amounts of land and pesticides. Land could be used for food instead of biofuels. Some pesticides could pollute the air and water.

Biomass energy can also be a nonrenewable energy source. Biomass energy relies on biomass feedstocks—plants that are processed and burned to create electricity. Biomass feedstocks can include crops, such as corn or soy, as well as wood.

If people do not replant biomass feedstocks as fast as they use them, biomass energy becomes a non-renewable energy source. Hydroelectric Energy.

Hydroelectric energy is made by flowing water. Most hydroelectric power plants are located on large dams , which control the flow of a river. Dams block the river and create an artificial lake, or reservoir.

In any discussion about climate change , renewable energy usually tops the list of changes the world can implement to stave off the worst effects of rising temperatures. That's because renewable energy sources, such as solar and wind, don't emit carbon dioxide and other greenhouse gases that contribute to global warming.

Clean energy has far more to recommend it than just being "green. All of those factors have contributed to a renewable energy renaissance in recent years, with wind and solar setting new records for electricity generation.

For the past years or so, humans have relied heavily on coal, oil, and other fossil fuels to power everything from light bulbs to cars to factories.

Fossil fuels are embedded in nearly everything we do, and as a result, the greenhouse gases released from the burning of those fuels have reached historically high levels. As greenhouse gases trap heat in the atmosphere that would otherwise escape into space, average temperatures on the surface are rising.

Climate change encompasses not only rising average temperatures but also extreme weather events, shifting wildlife populations and habitats, rising seas, and a range of other impacts. Of course, renewables—like any source of energy—have their own trade-offs and associated debates.

One of them centers on the definition of renewable energy. Strictly speaking, renewable energy is just what you might think: perpetually available, or as the United States Energy Information Administration puts it, "virtually inexhaustible. It also doesn't encompass other low- or zero-emissions resources that have their own advocates, including energy efficiency and nuclear power.

Types of Renewable Energy Sources Hydropower: For centuries, people have harnessed the energy of river currents, using dams to control water flow.

Hydropower is the world's biggest source of renewable energy by far, with China, Brazil, Canada, the U. While hydropower is theoretically a clean energy source replenished by rain and snow, it also has several drawbacks.

Large dams can disrupt river ecosystems and surrounding communities, harming wildlife, and displacing residents. Hydropower generation is vulnerable to silt buildup, which can compromise capacity and harm equipment.

Drought can also cause problems. In the western U. Even hydropower at full capacity bears its own emissions problems, as decaying organic material in reservoirs releases methane. Dams aren't the only way to use water for power: Tidal and wave energy projects around the world aim to capture the ocean's natural rhythms.

Marine energy projects currently generate an estimated megawatts of power—less than one percent of all renewables—but the potential is far greater.

Wind: Harnessing the wind as a source of energy started more than 7, years ago. Now, electricity-generating wind turbines are proliferating around the globe, and China, the U.

From to , cumulative wind capacity around the world increased to more than , megawatts from 23, megawatts—more than 22 fold. Some people may object to how wind turbines look on the horizon and to how they sound, but wind energy, whose prices are declining, is proving too valuable a resource to deny.

While most wind power comes from onshore turbines, offshore projects are appearing too, with the most in the United Kingdom and Germany. The first U. offshore wind farm opened in in Rhode Island, and other offshore projects are gaining momentum.

Wind Soruces solar are sougces a clean energy Low glycemic for inflammation reduction. Renewable power is suorcesas innovation brings down costs and starts to deliver on the source of a clean energy future. American solar and wind Improve digestion naturally are breaking records and being integrated into the national electricity grid without compromising reliability. Biomass and large hydroelectric dams create difficult trade-offs when considering the impact on wildlife, climate change, and other issues. Renewable energy, often referred to as clean energycomes from natural sources or processes that are constantly replenished. For example, sunlight and wind keep shining and blowing, even if their availability depends on time and weather.
