Renewable Energy
Resources

Due to the increased rates of Global
Warming and Carbon Emissions Co2 the world needs to find cleaner renewable forms of energy
production.
On average, electricity production sources emit about
1.3 lbs CO2 per KWh of energy
produced. This number varies greatly from area to area.
- The world-wide average is
4 tons of carbon dioxide CO2 emitted per person per year.
- The average of all industrialised nations is about 11 tons of
carbon dioxide CO2 per
person per year.
- In America the average is about 25 tons of carbon dioxide
CO2per person
per year.

Solar Power
There are a number of ways that the power of the sun
can be used to create clean renewable forms of energy.
Sunlight can be converted
directly into electricity using photovoltaics (PV). This is the process that first
comes to mind, for most of us, when we think about solar power. This is the technology used in making Solar
Panels. This process directly converts sunlight into DC electricity.
Sunlight can be converted indirectly into
electricity, also. This process is concentrating solar power (CSP). This focuses the
sun's energy to boil water to create steam which is then used to generate electricity. This system uses lenses or
mirrors and tracking systems to focus a large area of sunlight into a small beam generating high degrees of heat
for creating the steam.
The sun's energy can also be used for
solar water heating. Solar water heaters can be a cost-effective way to generate hot water for your home. They
can be used in any climate, and the fuel they use is free.

Wind Power
Wind power is the conversion of wind energy into a useful form of
energy, such as electricity, using wind turbines. Technologies are advancing at a very rapid rate in this
area.
