Solutions for power crisis in Sri Lanka

Shanika Lakmali

Population of Sri Lanka in 2004 was around 19.46 million, with population growth rate of 1.1% as compared to 1.3% in 2003 (Central Bank, 2005, 2004).So the population has grown up very rapidly. Energy consumption also increased with population growth rate & development. In the Past years most of the energy requirements were provided by hydro power generations. The use of petroleum in power generation has been rapidly increasing due to the increased use of thermal power, in the absence of alternative energy sources and the non-implementation of planned coal power and hydropower projects. Fossil fuels have to import from other countries. They are limited in supply. That’s why it’s better to go for other alternative energy sources. Such as biomass energy, solar power, wave power, nuclear power, wind power & bio gas.

First solution is construct mini hydro power plants related to the canals & small water falls. They can generate electricity for the isolated villages called off grid electricity & to the main grid electricity. Second one is thermal electricity generation by fossil fuels. The main environmental effect is the emission of green house gasses to the atmosphere. Biomass energy is most important renewable energy source. There is huge potential to develop dendro power plants in the country. Create employment opportunities, save foreign currency, improve rural development are the benefits of biomass energy. Wind power is the other energy source. We tend to build many of these towers together, to make a "wind farm" and produce more electricity. The more towers, the more wind, and the larger the propellers, the more electricity we can make. It’s only worth building wind farms in places that have strong, steady winds, although boats and caravans increasingly have small wind generators to help keep their batteries charged. Energy obtained by nuclear fission & nuclear fusion reactions. But most commonly used nuclear fission reactions. Wave & tidal power are energy sources from the sea.

In Sri Lanka large amount of power generation from thermal power. Mini hydro-power projects very suitable for our country. Also there is a huge potential to develop dendro power plantations in rural areas. Solar home systems good solution for the power generation in dry zone. Since the political instability Nuclear power not suitable as a alternative energy source. Tidal wave plantation have to have more capital investment. it’s a problem. So construction suitable, when under donations of developed countries.

Government should actively participate in promoting alternative energy sources. Private sector should be encouraged to make small renewable electricity plantations. Promote the use of high value public services. (solar powered refrigeration, solar PV or micro-hydro for telecommunication).Establish fuel plantations in coconut estates like crop areas can earn additional income Promote Agro based industries to run their own produced biomass energy. Use plant and animal wastes to produce fuels such as methanol, natural gas, and oil. Biomass energy systems can related to the reduction of agricultural waste disposal problem. Power crisis can be alleviate to some extends by establishing renewable energy plantations in the country.
