Heat generated from this process drives steam turbines which in turn produce electricity. Solar energy is captured and used locally. Solar produces either thermal energy, stored in water tanks, or electricity, stored in batteries. Solar energy is used primarily for space heating and water heating. Electricity produced by solar energy is too expensive to be widely used, but is expected to cost less in the near future, as energy costs rise, and solar technology improves.
Modern windmills produce a significant amount of electricity in California.
More use is now being made of fuels such as firewood, and agricultural and industrial waste products to generate electricity. This energy technology taps heat from deep below the earths surface to superheat steam used to dive turbines. Form work groups and develop reports on the major sources of energy and alternatives to these sources. B. Electricity for pumping irrigation water, processing and refrigeration. C. Natural gas for producing fertilizer, heating greenhouses processing food products.
