Clean Energy Private Limited
Clean energy is the provision of energy such that it meets
the needs of the present without compromising the ability
of future generations to meet their needs. A broader interpretation
may allow inclusion of fossil fuels as transitional sources
while technology develops, as long as new sources are developed
for future generations to use. A narrower interpretation
includes only energy sources which are not expected to be
depleted in a time frame relevant to the human race, which
can potentially also include nuclear power if it is utilized
differently from the current manner.
Clean energy sources are most often regarded as including
all renewable sources, such as biofuels, solar power, wind
power, wave power, geothermal power and tidal power. It
usually also includes technologies that improve energy efficiency.
Conventional fission power is sometimes referred to as sustainable,
but this is controversial politically due to concerns about
peak uranium, radioactive waste disposal and the risks of
disaster due to accident, terrorism, or natural disaster.
Clean energy includes natural energetic processes that
can be harnessed with little pollution. Anaerobic digestion,
geothermal power, wind power, small-scale hydropower, solar
energy, biomass power, tidal power, and wave power fall
under such a category. Some definitions may also include
power derived from the incineration of waste.
Some people, including George Monbiot and James Lovelock
have specifically classified nuclear power as green energy.
Others, including Greenpeace disagree, claiming that the
problems associated with radioactive waste and the risk
of nuclear accidents (such as the Chernobyl disaster) pose
an unacceptable risk to the environment and to humanity.
No power source is entirely impact-free. All energy sources
require energy and give rise to some degree of pollution
from manufacture of the technology. The world demand for
energy is rapidly increasing. We need energy to warm our
homes, to cook our meals, to travel and communicate, and
to power our factories. The amount of energy available to
us determines not only our standard of living, but also
how long we live. Detailed statistics from many counties
show that in countries where the available energy is 0.15
tons of coal equivalent per person per year the average
life expectancy is about forty years, whereas countries
in Europe and America where the available energy is a hundred
times greater have an average life expectancy of about seventy-five
years. It is well to remember that a shortage of energy
is a minor inconvenience to us, but for people in poorer
countries it is a matter of life and death.
