In some places, such as Iceland, the heat is so close to the surface it can be easily used as an energy-source. In other places holes must be drilled down through rocks to reach the heat. Geothermal energy is harnessed for cooking, bathing, space heating, electrical power generation, and other uses.
Real life example 
It is when earth’s heat comes from the interior of the earth and we take the heat to make energy or electricity ]]> 2018-03-07 18:03:25 UTC https://padlet.com/ram4959/26ukwyolnosr/wish/239305229 ram4959 https://padlet.com/ram4959/26ukwyolnosr/wish/239310250 A fossil fuel is a natural substance formed from the buried remains of ancient organisms that can be used as a source of energy. Fossil fuels formed over millions of years as heat and pressure from layers of sediment changed the decayed organic remains into materials such as coal and petroleum. The energy in fossil fuels is the energy from sunlight stored in the tissues of the buried organisms.
Real life example 
Fossil fuels is when coal is turned into energy.

Solar energy is the source of energy for pohotsyntsis .It provides the warmth necessary for plants and animals to survive. The heat from the Sun causes water on
the Earth’s surface to evaporate and form clouds that eventually provide fresh rainwater.

Solar power is when power is collected from the sun and turned  into energy.]]> 2018-03-07 18:16:12 UTC https://padlet.com/ram4959/26ukwyolnosr/wish/239312938 ram4959 https://padlet.com/ram4959/26ukwyolnosr/wish/239316905
Wind is a clean and inexhaustible source of energy that can be harnessed to produce power. Historically, wind power in the form of windmills has been used for centuries for such tasks as grinding grain and pumping water. Today sophisticated wind machines known as wind turbines are used in many parts of the world to convert the kinetic energy of wind to electricity.
Real life example 
Wind power is when wind mill collect wind energy and make it into electricity.

Since such feedstock material can be replenished readily, biofuel is considered to be a source of renewable energy, unlike fossil fuels such as petroleum, coal, and natural gas. Biofuel is perceived by its advocates as a cost-effective and environmentally benign alternative to petroleum and other fossil fuels, particularly within the context of rising petroleum prices and increased concern over the contributions made by fossil fuels to global warming. Many critics express concerns about the scope of the expansion of certain biofuels because of the economic and environmental costs associated with the refining process and the removal of vast areas of arable land from food production.

Real life example 

Wind energy is renewable because the wind will never out .]]> 2018-03-08 16:21:24 UTC https://padlet.com/ram4959/26ukwyolnosr/wish/239747888 ram4959 https://padlet.com/ram4959/26ukwyolnosr/wish/239799134  In the generation of hydroelectric power, water is collected or stored at a higher elevation and led downward through large pipes or tunnels (penstocks) to a lower elevation; the difference in these two elevations is known as the head. At the end of its passage down the pipes, the falling water causes turbines to rotate. The turbines in turn drive generators, which convert the turbines’ mechanical energy into electricity.

Real life example 

When the force of water is turned into energy and electricity.]]> 2018-03-08 17:37:14 UTC https://padlet.com/ram4959/26ukwyolnosr/wish/239799134 ram4959 https://padlet.com/ram4959/26ukwyolnosr/wish/239804741 Coal, which forms over millions of years, is a source of energy. Once it is used, it cannot be made again. It is nonrenewable. Energy from the Sun is never used up. It is a renewable resource.

Real life example 

When fuel is turned into ash so it can’t use it again.

Fossil fuels are finite resources, however. This means that they are available on Earth only in limited supplies and will run out one day. Fossil fuels also add carbon dioxide to the atmosphere when they are burned. Scientists believe that this contributes to global warming. Burning fossil fuels also adds other pollutants, such as carbon monoxide and nitrogen dioxide, to the atmosphere.

Real life example 

Solar power is an alternative energy source. Coal and gasoline are not alternative energy sources.
