Renewable
energy technologies provide many significant benefits,
both economic and environmental. They provide energy
in the form of electricity, motive power, or heat
without the use of fossil fuel. As a result, the
emission of greenhouse gases and local air pollution
are avoided. Renewable energy systems generally
have lower operation and maintenance costs since
they use the sun or the wind as their fuel source.
Most operate quietly in contrast to the noise pollution
associated with small gas and diesel generators.
In many remote off-grid locations, commercial renewable
energy systems provide the lowest life-cycle energy
cost.

is a breakdown of the advantages of photovoltaic
water pumping.
