TYPES OS RENEWABLE ENERGY RESOURCES

Wind Power
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.
                                                                                                                                                                          
Solar Power
is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into electric current using the photoelectric effect.[1]
Commercial concentrated solar power plants were first developed in the 1980s, and the 354 MW SEGS CSP installation is the largest solar power plant in the world and is located in the Mojave Desert of California. Other large CSP plants include the Solnova Solar Power Station (150 MW) and the Andasol solar power station (100 MW), both in Spain. The 97 MW Sarnia Photovoltaic Power Plant in Canada, is the world’s largest photovoltaic plant.solar power

                                                                   geothermal energy

                                                                                                                                                                   Hydro power he most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity. But hydroelectric power doesn't necessarily require a large dam. Some hydroelectric power plants just use a small canal to channel the river water through a turbine.                                                                                                                                                                                                                                                                                     geothermal energy is the heat from the Earth. It's clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

to be truly sustainable they need to be made more efficiently without using so many staple foods. And so scientists are developing new biofuels out of anything and everything, from plant waste to pond scum, from rotting garbage to whisky.

What are your ways to keep our environment clean and green?

I Will  throw my garbage in proper trash can and i will plant trees so that no more landslide and i will not burn plastic. I will not cut trees and i will not waste papers or tissues, i will recycle my things i will not waste things. I will not throw my  garbage any were so that  no more global warming and  i will not waste my things so that i cannot buy many things.

I will tell to my friends that don't waste things and don't garbage any were so that no more pollution in our earth and mother will not be angry. I will tell to my friends that help me plants trees and i will tell them to her / his father that don't cut tress so that no more landslide and we need our earth clean so that it will not smell bad and it will not cause or family or houses that we want to save it. I will make my earth clean and green so that no more landslide,pollution,and global warming and i can save my earth.
