Renewable energy is clean, affordable and infinite. It doesn't produce
emission and can help imaintain clean air and water. The two most common forms
of renewable energy are solar power and wind power.
Solar Power
Solar energy is used to generate electricity which can be used to power
many household appliances like the air conditioning unit, heater and range. It
is collected and converted during the day when the sun is at its peak; and used
the most at night. Harnessing solar energy reduces carbon footprint because no
fossil fuels are burned. It's most cost effective when power or electricity
rates go up.
Wind Power
An example of one of the common ways to harness wind energy is the wind
turbine or windmill. Wind turbines have blades more than 200 feet high which
are moved by wind power to create electricity. They provide unlimited clean
energy as opposed to energy from fossil fuels.
Wind turbines, like solar panels, are efficient but environmental
restrictions can limit their installation. While solar panels can be placed on
roof tops and can blend with the urban landscape, wind turbines are not that
easy to put up. Since these are huge structures, they are not fit in densely
populated urban places so they are rarely a good power
alternative in the city.
