Where does our energy come from?
Wind power is produced by wind turbines
This is not a very efficient process
No green house gases produced
It makes a noise which can be disturbing for those that live nearby
Can be dangerous if there are children nearby
it travels through pipes in the damn - gains kinetic energy and GPE, that spins generators that produce electricity.
dangers to the environment and citizens
can destroy habitats
can be used to heat water
no greenhouse gases
expensive to buy, cheap to run
doesnt work at night
doesnt work when there is no sun
can help people in remote areas
This kind of energy comes from the ground
water is sent underground, it is turned into steam by the heat of the rock. the steam turns turbines that then generate electricity.
This process is quite efficient
Process doesn't produce green house gases
This can destroy habitats
Bobs along the waves to produce energy
can produce much greenhouse gases
are hard to maintain, and expensive
uses the tide rise to turn turbines that generates electricity.
expensive to build
