Natural Resources of renewable energy

The majority of renewable energy technologies are powered by the sun. Earth’s atmosphere system is in equilibrium such that heat radiation into space is equal to incoming solar radiation, the resulting level of energy within the Earth-Atmosphere system can roughly be described as the Earth's "climate. Energy is dissipated around the globe in the form of winds and ocean currents. Wave motion may play a role in the process of transferring mechanical energy between the atmosphere and the ocean through wind stress. Solar energy is also responsible for this distribution.
Renewable energy flows involve natural phenomena such as sunlight, wind, tides, geothermal heat all of these are producers of renewable energy.
"Renewable energy is derived from natural processes that are replenished constantly. Renewable energy in its various forms is derived directly from the sun, or from heat generated deep within the earth. Thus renewable energy is generated from solar, wind, ocean, hydro power, biomass, geothermal resources, and biofuels along hydrogen derived from renewable resources.

Water Renewable Energy

Renewable Energy in water can be harnessed and used as water is about 800 times denser than air. Even a slow flowing stream of water, or moderate sea swell, can yield considerable amounts of renewable energy.
There are many forms of water renewable energy:
• Hydroelectric renewable energy is a term usually reserved for large-scale hydroelectric dams. Examples are the Grand Coulee Dam in Washington State and the Akosombo Dam in Ghana.
• Micro hydro renewable energy systems are hydroelectric power installations that typically produce up to 100 kW of power.
• Dam less hydro systems derive kinetic renewable energy from rivers and oceans without using a dam.
• Ocean renewable energy describes all the technologies to harness energy from the ocean and the sea.
o Renewable energy in marine current power, uses the kinetic renewable energy of marine currents.
o Tidal power captures renewable energy from the tides. Two different principles for generating renewable energy from the tides are used at the moment:
Tidal motion in the vertical direction: Tides come in, raise water levels in a basin, and tides roll out. Around low tide, the water in the basin is discharged through a turbine, exploiting the stored potential renewable energy.
Tidal motion in the horizontal direction: Uses tidal stream generators, like wind turbines but then in a tidal stream. Due to the high density of water, about eight-hundred times the density of air, tidal currents can have a lot of kinetic renewable energy.
o Renewable energy in wave power uses the energy in waves. Wave power machines usually take the form of floating or neutrally buoyant structures, which move relative to one another or to a fixed point. Renewable energy wave has now reached commercialization.
• Renewable energy in deep lake water cooling is an interesting phenomenon, although not technically an energy generation method, can save a lot of energy in summer. It uses submerged pipes as a heat sink for climate control systems. Lake-bottom water is a year-round local constant of about 4 °C.
Water has a lot of potential for producing green clean renewable energy, Dams and barrages all over the world are producing huge amount of Electricity and has hardly any carbon emissions.
