How is geothermal energy better than fossil fuels - 1 views
-
"Geo thermal systems heat and cool your house cheaper and better than fossil fuels will with gas going up pretty soon you would not be able to afford it. It might be costly to put one in your house initially but it will pay itself off in 3-5 years. Also there is a company called ECONAR that builds a heat pump that will cool, heat, and do 50 to 100% of your hot water heat. Fossil fuels also produce carbon dioxide when burnt, adding to the greenhouse gases and contributing to climate change."

"The Solutions With current technology, renewable energy sources like wind, solar, and geothermal can provide 96% of our electricity and 98% of our total heating demand - accounting for almost all of our primary energy demand."
Where does Wind Energy Come From? - 1 views
-
All renewable energy (except tidal and geothermal power), and even the energy in fossil fuels, ultimately comes from the sun. The sun radiates 174,423,000,000,000 kilowatt hours of energy to the earth per hour.

The sun radiates 174,423,000,000,000 kilowatt hours of energy to the earth per hour. In other words, the earth receives 1.74 x 10 17 watts of power . 1) About 1 to 2 per cent of the energy coming from the sun is converted into wind energy. That is about 50 to 100 times more than the energy converted into biomass by all plants on earth. 2)"

Sustainable energy is the sustainable provision of energy that meets the needs of the present without compromising the ability of future generations to meet their needs. Technologies that promote sustainable energy include renewable energy sources, such as hydroelectricity, solar energy, wind energy, wave power, geothermal energy, and tidal power, and also technologies designed to improve energy efficiency.

Hydrogen fuel - Wikipedia, the free encyclopedia - 0 views
-
Because pure hydrogen does not occur naturally, it takes energy to manufacture it. There are different ways to manufacture it, such as, electrolysis and steam-methane reforming process.
-
In electrolysis, electricity is run through water to separate the hydrogen and oxygen atoms. This method can be used by using wind, solar, geothermal, hydro, fossil fuels, biomass, and many other resources.
-
The more natural methods of making electricity (wind, solar, hydro, geothermal, biomass), rather than fossil fuels, would be better used as to continue the environment-friendly process of the fuel. Obtaining hydrogen from this process is being studied as a viable way to produce it domestically at a low cost. Steam-methane reforming process extracts the hydrogen from methane. However, this reaction causes a side production of carbon dioxide and carbon monoxide which are greenhouse gases and contribute to global warming.
