Identify some common sources of each type of electricity. They can be difficult, costly and dangerous to mine. Some contain impurities such as sulphur that pollute the atmosphere further when they burn, contributing to acid rain. Fossil fuels occur naturally in the earth and are the remains of living organisms from the geological past. They include oil and gas are chemicals made from molecules containing just carbon and hydrogen. After the life of PVs, they are recyclable and don't create environmental pollution.

Of those renewable energy sources hydropower is the biggest contributor contributing around 6 per cent of total electricity. Festival of Sacrifice: The Past and Present of the Islamic Holiday of Eid al-Adha. A nuclear reactor is basically a source of heat (from the decay of uranium) and that heat is transferred to water and that water boils and the high pressure steam from the boiler is vented through pipes to turn the blades on a turbine (like the wind turns the blades of a wind turbine) that in turn spins an electrical generator in which electric power is generated. Many coals when burned produce smoky flames. The oil-based fuels provide less energy per kilogram than natural gas. Water is available in plenty of amounts on earth. Disadvantages

One advantage is that it produces electricity on-demand.

These energy resources fall into two main categories, often called … These PV cells are totally made up of silicon which is the second most abundant element found on earth.

But, a large scale use might cause significant influence to the environment. Gas and oil may move through porous rocks and may even come to the surface. Over time, the layers of rocks in the Earth's crust move and may become squashed and folded. Furthermore, the combustion of coal also produces gaseous waste such as sulphur dioxide, nitrogen dioxide, and carbon monoxide etc. electricityMap is a live visualization of where your electricity comes from and how much CO2 was emitted to produce it. water), which can be used for other purposes. Will 5G Impact Our Cell Phone Plans (or Our Health?! It has fewer environmental impacts in compared to large dam. One drawback is that it produces harmful radiation which is life-threatening and extremely dangerous to health. In case of nuclear power, the energy is harnessed by the power that constrains in the nuclei of the atoms. This refined gas is used to create steam which in turn rotates turbines to produce electricity.

It is not considered as the true source of renewable energy. Sulphur dissolves into water and causes acid mine drainage which can influence thousands of miles from one to another country. The main sources of electricity are fossil fuels, nuclear power and renewable energy. Advertisement. Producing electricity energy by using wind power is limited to windy areas because the set-up cannot be installed everywhere, particularly on those areas where speed of wind is very slow.

Solar: The sun's rays can be easily used in the form of solar energy to minimize the problem of electricity. Since this gas cannot be used directly, it is refined.
It is a black solid that is reasonably soft. They include coal, oil and natural gas, which generate electricity when they burn in large electric power plants.

Coal: The nuclear lifecycle involves the mining of uranium ore, releasing radon, and producing large amounts of radioactive waste rock.

It is a finite resource and will eventually run out. Primary types can be used directly, as they appear in the natural environment: coal, oil, natural gas and wood, nuclear fuels (uranium), the sun (photovoltaic cell collection), the wind, tides, mountain lakes, the rivers (from which hydroelectric power can be obtained) and the Earth heat that supplies geothermal energy. It is thought that the current resources under the North Sea will last about another 20 years and the world resources will last for about 70 years. The main sources of electricity are fossil fuels, nuclear power and renewable energy. In some places, pockets of oil and gas can be found, because non-porous rocks have trapped them.

Wind turbines 4.

In both of the cases, a huge amount of heat is generated that helps to create steam which in turn rotates turbines and produces electricity.
The vast lands are required to grow more trees or crops that can be used as biomass-fuels. When gas and oil burn they produce mainly carbon dioxide and water, releasing the energy they contain.

The mountain top removal, open pit, and underground mining are a big cause of concern because many times rain water filter through coal mine and tailings. It is relatively easy to transport because it is a solid. The kinetic energy of flowing water can be used to rotate turbines that on the other hand produce hydroelectricity. When these fuels are burned they produce the gas carbon dioxide, which is a greenhouse gas and is a major contributor to global warming. Natural Gas: It is a cheap source of energy found in plenty of amounts on earth. This source of energy doesn't produce pollution however negligible amounts of water or air pollution may happen during the time of maintenance. It is thought that with new discoveries these fossil fuels will last well into the next century. Nuclear power is a nonrenewable energy source that uses radioactive materials as part of the process of heating water to generate electricity. It may cause cancer, genetic mutations, acute illness or even death at high doses. The kinetic energy of the rotating wind turbine helps to harness wind energy which is one of the easiest sources of renewable energy available in plenty of amounts. Secondary types come from the transformation of primary energy: for example petrol, that derives from the treatment of crude oil and electrical power, obtained from the conversion of mechanical energy (hydroelectric plants, Aeolian plants), chemical plants (thermoelectric), or nuclear (nuclear plants). Crude oil (oil obtained from the ground) is a sticky, gooey black stuff. They are called fossil fuels because they are thought to have been formed many millions of years ago by geological processes acting on dead animals and plants, just like fossils. This law states that energy can neither be created nor destroyed, merely transformed from one form to another. It is less expensive in comparison with other energy sources because it is easily available everywhere, especially in seabed, seashores, and hilly areas. It is non- biodegradable and stays in the atmosphere for thousands of years. Fact Check: What Power Does the President Really Have Over State Governors? At times, whole mountains are removed from their place and valleys are refilled by waste rocks. Much of the waste is added in the environment because of decommissioning of the old nuclear power plants. Wind: The kinetic energy of the rotating wind turbine helps to harness wind energy which is one of the easiest sources of renewable energy available in plenty of amounts. Gas and oil were formed from the remains of small sea creatures and plants that died and fell to the bottom of seas. Moreover, the capacity of electricity produced depends on size of the dams which are either large or small hydroelectric projects. Natural gas is a cheap source of energy and produces fewer pollutants such as particulates, sulphur dioxide and nitrogen oxide. SOURCES OF ELECTRICITY Competen cy based Learning Module (Electricity ) 2. suitable installations that can transform primary energy (non-transformed) into electric energy. Chemical Action It is a great deal of the world’s electricity produced by batteries. After 1950s, coal has become a major source of fuel to generate electricity in the United States. The turbine used in recent times is more lucrative as compared to the age-old windmill because of its sturdiness, power, and noiselessness.

Coal, oil and natural gas are fossil fuels. PVs don't produce pollution and require less maintenance.
