Renewable Sources of Energy: Promise for the future
Blue skies and green grass, we cannot have as long as we use
excess of gas. The aftermath and fallout of the excessive use of fossil fuels
has adversely affected man. As a consequence, the present condition of our
environment is like a patient lying in critical condition in the ICU.
Renewable energy sources are the best option available to
tackle the critical scenario. The sun is an abundant renewable energy resource.
In a country like India, if the abundant amount of sunlight available is
harnessed properly it could mean an end to the energy crisis. It is the most
abundant source of energy. The average global solar radiation is around 5
kilowatt hours (KWH) per square meter per day with the sunshine hours ranging
between 2300-4300 per year. India is in the sunny belt of the world. The
country receives solar energy equivalent to more than 5000 trillion KWH per
year, which is far more than its total annual energy consumption. Besides, it
is a renewable and clean energy source. Taking both environmental and economic
cost, solar energy works cheaper than fossil fuel resources. Once we master
techniques to harness solar energy, it can be a vital source of power on all planets.
Solar energy could be a wonderful source of power generation
for future. There are many technologies available for conversion of solar
energy into solar power. For instance, solar photovoltaic (SPV) technology,
photo galvanic cells, solar steam generators (solar concentrating power), solar
tower or solar chimney, radio micrometers and thermopile are some of them.
It is the most relevant and appropriate time to harness
solar energy in areas, states, and regions in our country where hydro
electrical power generation plants are not viable. Installation of solar-power
generation plants in such areas won’t only solve the energy problems, but will
also ensure cleaner and purer environment.
The best option in front of us at present to tackle the
problems posed by fossil fuels is the option of using alternative sources of
energy. With energy consumption being the buzzword in developing economies
around the world, fears of an energy crisis looming ahead are not totally
unfounded. The non-renewable nature of fossil fuels makes complete dependence
on these for future energy needs a very dicey affair. Renewable energy sources
are the best option in the current scenario. And what can be a better renewable
resource than the sun? Besides, it is a renewable and clean energy source. Taking
both environmental and economic cost, solar energy works cheaper than fossil
fuel resources. Once we master techniques to harness solar energy, it can be a
vital source of power on all planets.
Imagining a future where clean air is no longer a dream and
our cities are not smog filled concrete jungles, could well become a reality in
the coming years if the world begins to increasingly adopt the use of cleaner
options like alternate-fuel vehicles. The rise in economic activity and the
burgeoning population have led to a tremendous demand in the transport sector,
especially in urban India. By 2020, India's urban population is expected to
grow fivefold to a staggering 200 million while pollution is expected to grow
seven times. With this tremendous growth has emerged a very critical issue of
keeping air and noise pollution in urban areas under control. If we can have
three lakh electric vehicles (EVs) on the roads by 2020 including three
wheelers, cars and scooters, we would have reduced pollution by 16 lakh metric
tons, saved rupees 3700 crores in foreign exchange earnings and
substantially reduced healthcare costs.
There is no dearth of alternative sources of energy, if we
have a will to harness them. All that is required is a shift in our outlook and
concern for the future. We must replace the existing fuels with alternative
green-fuels for a better and healthier tomorrow.
In conclusion it can be said that if we have to save our health and environment from the adverse effects of using fossil fuels, frugal consumption, and replacing the fossil fuels with alternative sources of energy are the two viable options. We must switch over to them as early as we can for a brighter, healthier and safer future!
