Energy development is the effort to provide sufficient primary energy
sources and secondary energy forms for supply, cost, impact on air
pollution and water pollution, mitigation of climate change with
renewable energy. Technologically advanced societies have become
increasingly dependent on external energy sources for transportation,
the production of many manufactured goods, and the delivery of energy
services. This energy allows people who can afford the cost to live
under otherwise unfavorable climatic conditions through the use of
heating, ventilation, and/or air conditioning. Level of use of external
energy sources differs across societies, as do the climate, convenience,
levels of traffic congestion, pollution and availability of domestic
energy sources. All terrestrial energy sources except nuclear,
geothermal and tidal are from current solar insolation or from fossil
remains of plant and animal life that relied directly and indirectly
upon sunlight, respectively. Ultimately, solar energy itself is the
result of the Sun\\\\s nuclear fusion. Geothermal power from hot,
hardened rock above the magma of the Earth\\\\s core is the result
of the decay of radioactive materials present beneath the Earth\\\\s
crust, and nuclear fission relies on man-made fission of heavy
radioactive elements in the Earth\\\\s crust; in both cases these
elements were produced in supernova explosions before the formation of
the solar system. Renewable energy is energy which comes from natural
resources such as sunlight, wind, rain, tides, and geothermal heat,
which are renewable (naturally replenished). In 2008, about 19% of
global final energy consumption came from renewables, with 13% coming
from traditional biomass, which is mainly used for heating, and 3.2%
from hydroelectricity. New renewables (small hydro, modern biomass,
wind, solar, geothermal, and biofuels) accounted for another 2.7% and
are growing very rapidly. The share of renewables in electricity gen
