They don't emit greenhouse gases, as the burning of fossil fuels does
Coal is used in furnaces to heat water in a boiler to superheated (above 100 degrees Celsius) temperatures, and this steam is used to drive a turbine which, in turn, drives an alternator. A hydroelectric plant uses the vertical fall of water to drive a water turbine which drives an alternator.
The reactor in a nuclear power plant generates heat to flash water to steam, which spins turbines that generate electricity. This is not really any different, in terms of steam cycle1, than a fossil plant. Its just that the source of heat is nuclear fission of (usually) uranium-235 instead of the burning of coal, oil, or natural gas. ----------------------------------------------------------------------------------------------- 1Well, its a little bit different because the nuclear steam supply cycle runs best on a slightly lower pressure and temperature than a fossil fuel plant steam cycle does. Other than that, the steam and generating parts of a nuclear plant are very comparable to a fossil plant.
Answer:The La Rance Tidal Power Plant has been in operation since 1966 and has a capacity of 240 MW.South Korea currently (July, 2012) operates the largest tidal power plant in the world.Jiangxia Tidal Power has been in operation since 1985, but only produces 3.2 MW.SeaGen, in Northern Ireland, produces 1.2 MW.In all, there are about 8 so far which produce more than 1 MW, and numerous smaller projects in operation.
Coal Advantage *World's most abundant fossil fuel; *Large resource base. *Relatively cheap to mine and transport by rail.
fossil fuels are from prehistoric plant and animals
A power plant burns fossil fuels such as coal, oil, or natural gas to heat water and produce steam. The steam then drives a turbine connected to a generator, which produces electricity. This process converts the chemical energy stored in fossil fuels into mechanical energy and then into electrical energy.
Ancient plant remains are buried and compacted until they form fossil fuels. There are 3 types of fossil fuels: Natural Gas Oil and Coal; the only solid fossil fuel, which is what you're looking for.
Fossil fuels come from fossilied plant matter in the ground. Alternative fuels are alternatives to fossil fuels, and these are mainly carbon fuels that take their carbon from carbon dioxide in the atmosphere (as fossil fuels do) but on a carbon cycle with a much shorter term. An example is wood, which can be burned as more trees are growing and absorbing carbon dioxide.
A power plant using fossil fuels must recover nitrogen, sulfur oxides and in the future carbon dioxide.
It is a plant resource. More info: Fossil fuels come from decayed plants and animals. Fossil fuels are a limited non renewable energy source. A plant resource can usually be regrown every year and therefore has no production limit.
Personally I used fossil fuels today to boil my kettle, run my laptop on the internet, drive to the shops. Later I will cook my evening meal. All these things use fossil fuels. Electric power uses fossil fuels that are burnt at the nearest power plant.
Yes, that's where it is usually believed that fossil fuels come from - and that's why they are called "fossil" in the first place.
Mostly fossil fuels but there is one nuclear plant in South Africa
Those are called fossil fuels.
We have to reduce our dependence on fossil fuels by moving to renewable energy. Stopping the burning of fossil fuels is the one big thing we have to do. The other thing to do is plant and nourish billions of trees all over the world to make up for our deforestation.
Biomass fuels and fossil fuels are both sources of energy that can be used to generate electricity and heat. They are both derived from organic matter, with biomass fuels coming from recent plant material and fossil fuels coming from ancient plant and animal remains. Both types of fuel release carbon dioxide when burned, contributing to greenhouse gas emissions.
