Potential For Gliricidia Based Dendropower In Sri Lanka

P. L. A. M. C. Wijewarnasuriya

These days Sri Lanka has been facing a power crisis. When considering the national grid, about 60% is contributed by fossil fuels. Sri Lanka does not have fossil fuel resources and being a developing country, Sri Lanka has to spend lot of money for importing crude oil and refined oil. As a result of that, Sri Lanka has to go to an alternative energy source.

About 2-3 decades ago, people thought that, by developing the hydropower projects, power crisis can be solved. But all of us had to experience power cuts about 4 years ago, due to lack of rainfall. Climatic changes can directly affect on hydropower plants. Therefore, Sri Lanka should attention on non-conventional renewable energy sources such as dendropower.

Dendropower is , energy produced by using biomass. As biomass, Gliricidia biomass can be used. Gliricidia sepium is an ideal species for generating dendropower in Sri Lanka as it is a common species which has a rapid growth rate. By maintaining Gliricidia plantations for energy production, additional benefits can also be obtained by people in rural areas. Gliricidia based dendropower is a cheap energy source compared to fossil fuels. And it is also an environmental friendly energy source.

Currently, dendropower is already used in Sri Lanka. Therefore, there is a great potential for Gliricidia based dendropower in Sri Lanka.A
