Solar Energy Basics - - - Where Do You Think Our Energy Sources Are Going To Be In A Few Years?
Solar is the Latin word for sun—a powerful source of energy that can
be used to heat, cool, and light our homes and businesses. That's
because more energy from the sun falls on the earth in one hour than is
used by everyone in the world in one year. A variety of technologies
convert sunlight to usable energy for buildings. The most commonly used
solar technologies for homes and businesses are solar water heating,
passive solar design for space heating and cooling, and solar
photovoltaics for electricity.
Businesses and industry also use these technologies to diversify
their energy sources, improve efficiency, and save money. Solar
photovoltaic and concentrating solar power technologies are also being
used by developers and utilities to produce electricity on a massive
scale to power cities and small towns.
These technologies harness heat from the sun to provide electricity for large power stations.
These technologies harness heat from the sun to warm our homes and businesses in winter.
These technologies convert sunlight directly into electricity to power homes and businesses.
These technologies harness heat from the sun to provide hot water for homes and businesses.
These technologies use solar energy to heat or cool commercial and industrial buildings.
This is a short lesson in Solar Energy, one of the renewable sources of energy
that is fast becoming popular. There are many alternative energy sources an
some of them are being used effectively already.
