Science of Renewable Energy.

от Riley Wong

Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale

Renewable energy is also the most economic solution for new grid-connected capacity in areas with good resources. As the cost of renewable power falls, the scope of economically viable applications increases.

As we see, water means life

Such as:

Geothermal heat

is thermal energy generated and stored in the Earth. It's the energy that determines the temperature of matter

Waves

is the transport of energy by ocean surface waves, and the capture of that energy to do useful work – for example, electricity generation, water desalination, or the pumping of water (into reservoirs)

Tides

also called tidal energy, is a form of hydropower that converts the energy of tides into useful forms of power, mainly electricity

Rain

is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides suitable conditions for many types of ecosystems, as well as water for hydroelectric power plants and crop irrigation

Wind

is the flow of gases on a large scale. On the surface of the Earth, wind consists of the bulk movement of air

Sunlight

is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light

We can survive thank to renewable energy

Renewable energy technologies are getting cheaper, through technological change and through the benefits of mass production and market competition.

Renewable energy is the chance for a better life - environmentally

From what we derive the greatest benefit?

geothermal power 1,4%

Sslar power 2,4%

biomass 7,7%

wind power 12%

water power 71%

Renewable energy is our future

Hydro-electricity and geothermal electricity produced at favourable sites are now the cheapest way to generate electricity

Renewable energy will never end if we take care of it now

Renewable energy is also a huge savings

Main Renewable energy is our chance to live

Natural sources of energy

Renewable energy sources are produced to replace renewable sources of energy that used to be over. That soon could happen with:

natural gas

petroleum

peat

uranium

lignite

coal

Renewable energy replaces conventional fuels in four distinct areas:

rural (off-grid)

motor fuels

hot water/space heating

electricity generation
