Renewable energy resources are kind of those energy which are not destructing itself for producing energy for us, such as wind, solar and hydropower. This kind of energy offer clean alternatives to fossil fuels. They produce little or no pollution or greenhouse gases, and they will never run out.
The best energy resources we have in this planet is The sun. Sunlight, or solar energy, can be used for heating, lighting and cooling homes and other buildings, generating electricity, water heating, and a variety of industrial processes.
Moreover, Most forms of renewable energy come either directly or indirectly from the sun. For example, heat from the sun causes the wind to blow, contributes to the growth of trees and other plants that are used for biomass energy, and plays an essential role in the cycle of evaporation and precipitation that makes hydropower possible.
So We can call The Solar Energy Resource as "Premio resource of Recyclable Energy".
After Solar power, we can assume Wind is secondary resources as recyclable energy generating factor. Wind is the movement of air that occurs when warm air rises and cooler air rushes in to replace it. The energy of the wind has been used for centuries to sail ships and drive windmills that grind grain.
At present, researchers are expressing their own view for wind energy which is captured by wind turbines and used to generate electricity.
Hydropower
This is also secondary resources of recyclable energy. Where Water flowing downstream powerfully there it is a powerful force.
As we know, Water is a renewable resource, constantly recharged by the global cycle of evaporation and precipitation. The heat of the sun causes water in lakes and oceans to evaporate and form clouds. The water then falls back to Earth as rain or snow, and drains into rivers and streams that flow back to the ocean. Flowing water can be used to power water wheels that drive mechanical processes. And captured by turbines and generators, like those housed at many dams around the world, the energy of flowing water can be used to generate electricity.
Biomass Energy
Now a days, Biomass has been an important source of energy.
With wood , people are promoting the most common source of biomass energy, but other sources of biomass energy include food crops, grasses and other plants, agricultural and forestry waste and residue, organic components from municipal and industrial wastes, even methane gas harvested from community landfills.
Biomass can be used to produce electricity and as fuel for transportation, or to manufacture products that would otherwise require the use of non-renewable fossil fuels.
Hydrogen
Primarily, we can say this is next-generation technology as recyclable energy resource. Hydrogen has tremendous potential as a fuel and energy source, but the technology needed to realize that potential is still in the early stages.
Hydrogen is the most common element on Earth—for example, water is two-thirds hydrogen—but in nature it is always found in combination with other elements. Once separated from other elements, hydrogen can be used to power vehicles, replace natural gas for heating and cooking, and to generate electricity.
Geothermal Energy
The heat inside the Earth produces steam and hot water that can be used to power generators and produce electricity, or for other applications such as home heating and power generation for industry.
Geothermal energy can be drawn from deep underground reservoirs by drilling, or from other geothermal reservoirs closer to the surface.
The ocean, the big ocean. As we know we are surroundings by these oceans and it has provides several forms of renewable energy, and each one is driven by different forces.
Energy from ocean waves and tides can be harnessed to generate electricity, and ocean thermal energy—from the heat stored in sea water—can also be converted to electricity. Using current technologies, most ocean energy is not cost-effective compared to other renewable energy sources, but the ocean remains and important potential energy source for the future.
All above, with some home and with some desire to make our planet alive.
