"Wind is caused by differences in atmospheric pressure created, in large part, by the unequal heating of the earth's surface by the sun."

"What is geothermal energy? Simply put, it is energy from the Earth. Geo refers to the solid part of the Earth and thermal refers to heat energy. Anywhere the Earth's surface is in close proximity to magma or volcanic activity under or near the Earth's surface, we can harness the energy. According to the Department of Energy,"Geothermal energy technologies use the heat of the earth for direct-use applications, geothermal heat pumps, and electrical power production. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface and down even deeper to the extremely high temperatures of molten rock called magma. Three power plant technologies are being used to convert hydrothermal fluids to electricity. The type of conversion used depends on whether the fluid is steam or water and its temperature."

" wave energy is very close to being competitive with installed costs that suggest electrical charges of less than $.05 per KWh; which makes it competitive with fossil fuel generators. But that figure doesn't take into account the fact that wave energy is intermittent and variable. Even in the most active wave areas, there are many days with little wave activity."

The second type is based on utilizing the fast-flowing marine currents caused by tidal action....it is a truly sustainable energy source which is also very predictable. It is not subject to the vagaries of weather or climate change, and while the energy varies, it follows a predictable pattern that is known many years in advance.

" costs are expected to fall to between 5 and 7 cents/kWhr."

"Sustainability is the capacity to endure"

"Bio-fuel is produced directly from plant matter typically corn, sugar cane, sugar beets, or cellulose transforming it into alcohol. Fossil fuels are produced by either the decomposition of plant or animal matter over long periods of time under certain conditions such as high temperature and "

"What is sustainability? Sustainability is based on a simple principle: Everything that we need for our survival and well-being depends, either directly or indirectly, on our natural environment.  Sustainability creates and maintains the conditions under which humans and nature can exist in productive harmony, that permit fulfilling the social, economic and other requirements of present and future generations."

"The hydrogen economy is a proposed system of delivering energy using hydrogen. The term hydrogen economy was coined by John Bockris during a talk he gave in 1970 at General Motors (GM) Technical Center.[1] Hydrogen advocates promote hydrogen as a potential fuel for motive power[2] (including cars and boats), the energy needs of buildings and portable electronics. Free hydrogen does not occur naturally in quantity, but can be generated by steam reformation of hydrocarbons, water electrolysis or by other methods. Hydrogen is thus an energy carrier (like a battery), not a primary energy source (like coal). The feasibility of a hydrogen economy depends on issues of electrolysis, energy sourcing, including fossil fuel use, climate change, and sustainable energy generation."

"Geothermal energy uses hot water or steam from deep in the Earth. As a consequence it does not require fuels which produce emissions. However there are hot water (condensate) releases which may cause thermal pollution."

"The history of geothermal power can be traced back to over 10,000 years ago to the American Paleo-Indians at their settlement in hot springs. This history has been uncovered through the use of archeology and shows the Indians used the hot springs for activities including, bathing and heating. It is also believed the springs were seen as a healing source."

What is climate change

"First, let's clarify where waves come from: sun makes wind and wind makes waves."

" 13kW PEM fuel cell (Photo: Ballard Power Systems, Inc.) The process is essentially the reverse of the electrolytic method of splitting water into hydrogen and oxygen. In the fuel cell, the cathode terminal is positively charged and the anode terminal is negatively charged. These electrodes are separated by a membrane. Hydrogen gas is converted into electrons and protons (positive hydrogen ions) at the anode. The protons pass through the membrane to the cathode, leaving behind negatively charged electrons. This creates a flow of direct current electricity between the terminals when connected with an external circuit. This current can power an electric motor placed in this circuit. The hydrogen ions, electrons, and oxygen combine at the cathode to form water, the only byproduct of the process"
