power-generating capacity able to meet all needs. Nuclear Power is the most environmentally favorable way of producing electricity on a large scale. For example‚ a gram of uranium‚ which is used as fuel for Nuclear Power‚ produces energy as much as four tons of coal. Wood produces even less energy. Nuclear Power produces huge amounts of energy from small amounts of fuel. Nuclear Power is also able to meet industrial and city needs as compared to low-power technologies like solar that might meet only local‚ residential

For example‚ the internet facilitates the communication between the diversity groups of people.

In other cases‚ the tailings dam can overflow‚ and even breach‚ during periods of heavy rain. 4. Underground coal mining can require the removal of almost an entire layer of material deep under the surface. When the timber supports collapse‚ this can lead to subsidence. The subsidence can mean economic loss to people above or damage to natural areas. It can even

the Industrial Revolution began around 1750‚ human activities have contributed substantially to climate change by adding CO2 and other heat-trapping gases to the atmosphere. The main human activity that emits CO2 is the combustion of fossil fuels (coal‚ natural gas‚ and oil) for energy and transportation‚ although certain industrial processes and land-use changes also emit CO2. Electricity is a significant source of energy used to power homes‚ business‚ and industry. The combustion of fossil fuels

Fossil fuels have promoted global commerce and are behind many of the greatest technological and social innovations of our day. “Fossil fuel is made up of‚ oxidized and decayed animal and vegetable materials‚ specifically coal‚ peat‚ lignite‚ petroleum and natural gas” (Sica‚ 2011). We retrieve these fuels from under the ground and under water and then use this for electricity. The problem with this method is the over spill into the oceans and above ground. Some of the

Peak oil is often confused with oil depletion; peak oil is the point of maximum production while depletion refers to a period of falling reserves and supply It is estimated that the world may have enough oil to year 2030 at current consumption‚ and enough natural gas to year 2060 if all known reserves were recoverable.
