Renewable energy resource of Sri Lanka! A review
Abstract
Energy and related sectors play a key role in the developmental profile of Sri Lanka. Energy demand is going up and up with time due to population growth and industrial revolutions. In order to meet such growing needs probably we are relying on fossil fuel in a large fraction, which is leading to many negative environmental impacts. Hence the government decided to take off many long term as well as short term planes to promote renewable energy sector in Sri Lanka as it gives minimum impact to environment and its quality than the fossil fuel. This paper gives basic information about renewable energy resources of Sri Lanka and their development &future perspectives.

Introduction
Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale. Types of renewables include solar energy, wind energy, tidal energy and geothermal energy. Energy can be called renewable if it can neither run out nor be easily replaced (like slow-growing trees).Renewable energy is any form of energy, which can be used by the present generation without affecting the future generation'sability and right to use the energy resource. The basic forms of renewable energy are based on solar energy. All these renewable energy forms depend on the solar radiation, except geothermal energy, which again is a renewable energy resource, independent of solar energy. (11) Renewables are great for our energy portfolio because they are inexhaustible and won’tpollute the planet. However, nearly every town has access to sunlight, wind, and the geothermal power from the Earth. therefore harnessing these sources of renewable energy could be a great democratizing force, offering affordable and plentiful power to every corner of the globe. It is therefore important to propose possible renewable energy resources to meet the energy demand without polluting the environment and quality.
Conclusion
Requirement of energy in Sri Lanka also increasing in an increasing rate like other countries, So Energy needs to be conserved to protect our environment from drastic changes, to save the depleting resources for our future generations. The rate at which the energy is being produced and consumed can damage our world in many ways. In other words, it helps us to save the environment. We can reduce those impacts by consuming less energy. The cost of energy is rising every year. It is important for us to realize how energy is useful to us and how can we avoid it getting wasted.
Other prominent strategy is utilization of renewable energy. The vast renewable energy resource base of Sri Lanka will be developed to increase the dominance of indigenous energy in both electricity and thermal energy supplies. This initiative will cover the whole value chain of the electricity sector from electrification of remote locations through off-grid solutions to large scale infrastructure development to absorb wind, solar, remaining hydro and other renewable energy resources based power generation to the national grid.
