[Energy resources]:The 2 broad typesPros and Cons of each typeWays in which they are harnessedThere two main types of energy these are:1. Potential energy2. Kinetic energyPotential energyPotential energy is energy stored due to position. The following are some example in which potential energy can be found.1. Wound-up springWhen a spring of a dock work toy car unwinds, the stored energy in the spring drives the wheels and the car moves. The wound-up spring is said to posse potential energy.2. A raised objectAn object raised to a height above the Earth's surface posse potential energy due to its position. Other objects possessing potential energy include;3. Cultputt with a stone4. An arrow pulled on the bow5. MagnetsKinetic energyThis is the energy possessed by a moving body.Example include the following:1. A moving carWhen a car is moving it is said to posses kinetic energy. This energy depends on the moving.2. When a boulder on a top of a hill is hurled down its energy changes from potential energy to kinetic energy.Energy resourcesEnergy resources are stores of convertible energy. These resources are divided into two groups:Non renewable resources which include fossil fuels (e.g. coal, oil and gas) and nuclear fuels.Renewable resources, which include wind, tidal, geothermal, and hydroelectric power.Non renewable sourcesAre used in thermal power stations to produce heat energy that turns water into steam. The steam drives turbines and in turn drives the generators that produce electrical energy.Fossil fuelsCoal, oil and natural gas are all called fossil fuels because they are fossilized remains of plants and animals that live million of years ago. Burning fossil fuels release chemicals that cause acid rain, and its gradually increasing the carbon dioxide in the atmosphere causing global warming.OilLargest energy source. Future use will depend on shift from growing to declining supply.CoalThe most plentiful fossil fuel. Coal use is growing, intensifying problems of acid rain and carbon dioxide.Natural gasLikely to replace oil...

Exploring Energy Resources Essay

3509 words - 14 pages , Oil, and Gas. Geothermal energy is heat energy that comes from inside the earth. The resources that come from geothermal energy have a very wide range. It can range from the shallow ground. Hot rocks & water are included in this. The hot water and rocks are found just a few miles beneath the surface of the earth. When you go down deeper and deeper is when you reach the extremely high temperatures and pressure. The molten rock down there is called

Alternative Energy Resources

1150 words - 5 pages The energy that is used today comes from fossil fuels, which is a nonrenewable limited resource that will eventually be used up. Alternative energy sources such as solar, hydroelectric, geothermal and wind energies can be used, to conserve the planets limited natural resources. Alternative energy is the use of another energy without the burning of fossil fuels and break up on atoms. Solar energy can be used to operate cars and provide

Future Energy Resources: Hydropower

The energy generated from hydropower plants can be used to power homes, businesses and factories. Globally the use of hydropower has increased rapidly between the years 2003 and 2009, and has continued to increase from 2009 to 2010. By 2010 use of hydropower reached a record of 3427 terawatt

Renewable Energy Resources and their Limitations

1977 words - 8 pages ago the figures were reverse. Fossil fuel provides only 5% of energy while the animals and humans supplied 94% of it (Grubb et. al., 2006). This extensive usage of fossil fuel seriously endangers the environment of our planet. Everyone is desperately trying to devise such energy resources that can not only save the planet from plunging deep into the pit of destruction and catastrophe but also will be more feasible economically. It has been
