Coal is found in China, India, and the United States. Wind If you have ever driven though Indiana, you have probably seen hundreds of windmills turning on the horizon. Wind power takes advantage of airflow to turn an electric generator. Although wind power is a variable power that depends on the weather, it is a stable source of energy over a long-term period.
It is a reliable resource to meet power needs. Nuclear power is produced by harnessing a process called nuclear fission. Nuclear fission is breaking apart bunches of neutrons by splitting spontaneously or on impact with another particle, with the release of energy. This happens within a nuclear reactor. The power plant harnesses the energy from the split by using a cooling chamber that removes the heat from the reactor core.
They do this by using a cooling system that generates steam, which powers a steam turbine. The turbine converts the steam to mechanical energy and then to electrical energy.
In this case, we burn coal to make hot water or steam , convert this to electricity, and then convert the electricity back to hot water in the house. The causes are complex and differ by state, but the replacement and refurbishment of infrastructure essentially, these are the poles and wires , compliance with reliability license conditions, and the building of new infrastructure to cater to peak demand played the largest role.
Peak demand typically occurs during heat waves and cold snaps, when three-quarters of all Australian households with air-conditioning turn on these appliances to get some respite from the elements.
One proposal for combating affordability is to introduce different electricity prices for different time periods of usage. This is known as cost reflective pricing. While not everyone may be able, or want, to make significant changes to the times when they use electricity, introducing such a scheme should at least allow consumers to make more informed decisions.
A major transformation in the Australian energy landscape, and one that poses a challenge for the traditional grid, is happening right outside your window. Households are becoming energy generators, with one in ten Australian homes having installed solar panels. Consumers are now pushing power back the other way and, although this is an overwhelmingly positive thing, the amount of electricity that will be generated by these households can be as difficult to predict as the weather itself.
Reducing peak demand, allowing renewable energy, and maintaining reliability are all possible. As part of the Future Grid Forum , CSIRO is working with the industry and government to ensure that when Australians boil the kettle in , we are using electricity generated from the most cost-competitive, low-emission energy sources possible.
Although most of us take the power grid for granted, it's anything but simple. There are , miles , kilometers of high-voltage power lines and , miles , kilometers of overhead transmission lines in the United States connecting electrical power plants to homes and businesses [source: DOE ]. Since large amounts of energy cannot be stored, electricity must be produced as it is used [source: EIA ]. The power distribution grid must respond quickly to shifting demand and continuously generate and route electricity to where it's needed the most.
The power grid is also evolving. Upgrades in technology now let us connect our own home-generated electricity to the grid — using solar panels or wind generators — and get paid back by utilities. The U. The smart grid project also will extend the reach of the grid to access remote sources of renewable energy like geothermal power and wind farms [source: DOE ].
