Alternative Energy includes three main groups: Renewable Energy
(Solar, Wind, Hydro, Geothermal, Biomass) Fuel Cells & Hydrogen
Energy Conservation and Enabling Technologies saves natural
resources is environmentally superior to conventional coal and
oil. Wind, flowing water, energy conservation and geothermal
heating are ancient but now employ new advanced technology.
Technologies such as solar cells, hydrogen and fuel cells and
ocean energy are relatively new. All of the technologies
operate. The present cost effectiveness of some of the newest
technologies varies. Alternative Energy does not include Coal
and oil are fossil fuels that cause environmental damage when
mined and release pollution when combusted. Alternative energy
is cleaner. There may be future technologies for the
transformation of coal to a clean source of energy. We do invest
in natural gas which is the cleanest of all hydrocarbons,
particularly when used in modern turbines and fuel cells.
Natural gas is often used to displace dirtier opti
