The most cost-effective methods to generate electricity today are hydro-electricity and geothermal electricity at favorable sites. Renewable energy, which is derived from naturally replenished resources, stands out as the most economical option for new grid-connected capacities in resource-abundant areas.
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:
