Solar energy

Solar Energy

Solar Energy is collected by Solar panel

It is extremely healthy for the planet

Solar energy can be used to heat swimming pools and other things like that

It can help peoples power bills and reduce carbon emissions

Electrical generators work by mechanical energy transfer, . As the wind turbine causes the shaft of the generator to turn, a coiled wire attached to the shaft turns between two oppositely charged magnets. The rotation creates a difference in voltage on the two ends of the wire. In turn, the increase in electricity flows through the wire and to a main power line. The amount of electricity generated by the wind turbine depends on how much mechanical energy comes from the wind


Water energy

Water Energy

Water energy is made up of kinetic and potential energy.

We collect water energy in hydroelectric power plants.

We also collect the energy from the ocean by using wave and tides

It is very healthy for the Earth .


How to make water into energy

How to make water into energy

1To use water to generate electricity, you first need to go to the source---generally, a river, ocean currents, or a large body of water, such as a lake or a man-made reservoir. The most common hydropower method generally involves building a dam across a river and creating a lake or reservoir behind it to act as a power source.

2To begin generating electricity, the dam opens gates to allow water from the reservoir to flow through penstocks---large tubes inside the dam---where it turns the blades of turbines.

3The turbines attach to generators with long shafts, which create electricity with the spinning motion caused by the water rushing through the penstocks.

4The raw electricity created by the generators then travels to the utility company via transmission lines.

5Though other types of hydropower exist, we have yet to develop them for practical use on a mass scale.

6Tidal energy works much the same way as a dam, only the the tides, rather than a river or lake, act as the power source.

7Wave energy generation works by using the motion of the waves to push air through a cylinder, turning a turbine, which then turns the generator.

8Another experimental source, known as Ocean Thermal Energy Conversion (OTEC), works by using pressure to turn warm surface water into steam. The steam then spins a turbine, creating electricity.

Wind energy

Wind energy

It is collected by using turbines

originally the idea of the turbine was thought about in the Europeans

It is also very healthy for the Earth

It is a good idea to help stop carbon Wind power is produced by using wind generators to harness the kinetic energy of wind. It is gaining worldwide popularity as a large scale energy source, although it still only provides less than one percent of global energy consumption. The articles listed below explore wind power and its usage around the world.
