The sudden rise in gas prices have given companies the insensitive they need to start getting serious about renewable energy.  You can debate if we are running out of oil and never get a definite answer, but the fact of the matter is we should be using whatever the planet is providing us.  It was easy for companies to turn the other way when oil and natural gas were so cheap.  Well now that it is more politically correct and cost effective to start looking at new energy sources, we are seeing a new interest in renewable energy. 

Clean and Green Planet is the goal and we hope you visit our site frequently to checkout the latest articles about wind power, solar power and biomass.

Renewable Energy Basics

The United States currently relies heavily on coal, oil, and natural gas for its energy. Fossil fuels are nonrenewable, that is, they draw on finite resources that will eventually dwindle, becoming too expensive or too environmentally damaging to retrieve. In contrast, renewable energy resources—such as wind and solar energy—are constantly replenished and will never run out.

Solar -  Most renewable energy comes either directly or indirectly from the sun. Sunlight, or solar energy, can be used directly for heating and lighting homes and other buildings, for generating electricity, and for hot water heating, solar cooling, and a variety of commercial and industrial uses.

Wind -  The sun's heat also drives the winds, whose energy is captured with wind turbines. Then, the winds and the sun's heat cause water to evaporate. When this water vapor turns into rain or snow and flows downhill into rivers or streams, its energy can be captured using hydropower.

Biomass -  Along with the rain and snow, sunlight causes plants to grow. The organic matter that makes up those plants is known as biomass. Biomass can be used to produce electricity, transportation fuels, or chemicals. The use of biomass for any of these purposes is called biomass energy.

Hydrogen -  Hydrogen also can be found in many organic compounds, as well as water. It's the most abundant element on the Earth. But it doesn't occur naturally as a gas. It's always combined with other elements, such as with oxygen to make water. Once separated from another element, hydrogen can be burned as a fuel or converted into electricity.

Geothermal -  Not all renewable energy resources come from the sun. Geothermal energy taps the Earth's internal heat for a variety of uses, including electric power production, and the heating and cooling of buildings. And the energy of the ocean's tides comes from the gravitational pull of the moon and the sun upon the Earth.

Ocean -  The ocean can produce thermal energy from the sun's heat and mechanical energy from the tides and waves. NREL does not conduct research in ocean thermal energy or ocean mechanical energy. See the U.S. Department of Energy's Consumer Guide Web site for basic information ocean energy.

Hydropower -  Flowing water creates energy that can be captured and turned into electricity. This is called hydroelectric power or hydropower. NREL doesn't perform any research in hydroelectric power technologies. For more information on hydroelectric power, see the Hydropower Basics from the U.S. Department of Energy's Wind and Hydropower Technologies Program.
