Key Alternatives to fossil fuel energy sources
There are a number of available technologies being
used to generate energy (electrical and transportation fuel) that do not
consume fossil fuel and don't add carbon dioxide to the earth's
Solar Energy - Photovoltaic
Solar Energy - Thermal systems
The key principal of thermal solar systems to to
collect the heat from the sun and use it to warm up a fluid that will
transfer the heat to where it can be used. One example of this are the
solar thermal systems used for heating water systems to provide hot
water to a home or business.
The other major example of this is power stations
that concentrate a lot of solar heat to generate electrical power. These
are large investment systems that typically use mirrored collectors to
concentrate the heat energy and typically warm up a molten salt. This
molten salt is heated to a high temperature and then moved to a heat
exchanger that creates steam. The steam is then used to drive a
conventional power turbine.
