Concentrated solar power:
What is it?
· Use mirrors or lenses to concentrate a large area of sunlight, or solar thermal energy, onto a small
· Electrical power is produced when the concentrated light is converted to heat, which drives a heat
engine connected to an electrical power generator
· USA and Spain have many power stations for this
· $6001000 million to build a station
· 2227 plants world wide
· Renewable technology as it uses solar power
· Works even when sun isn't shining ­ reliable
· Cuts down on CO2 emissions as it is only produced when building the power plant
· Good option for countries such as Africa, Australia and some in the Mediterranean
· Africa can use energy to develop also sell on to make profit which aids their economy
· Quick to build the stations
· Reduces reliance on nonrenewable sources and on supplies of energy from other countries
· Fossil fuel supplies last longer
· Can be built in areas where human and animal populations are sparse e.g. outback and middle of the
· Technology is readily available
· Most efficient during the daylight hours
· Cannot be relied upon as primary electrical sources
· Even the systems that use heat storage techniques may stop producing electricity if it's overcast for a
number of days
· Small dish/engine systems cannot be economically used in a backyard to power a house, it is
currently too expensive
· Expensive transmission lines need to be installed in remote desert locations to get the useful energy
to market
· Electrical production may not be continuous so it takes a longer time for CSP systems to pay for
· Expensive to build power plants
