Climate change is one of the biggest problems facing the world today. Climate change refers to the changes of the climate in which bad phenomena that caused directly or indirectly by human activities. Global warming is one of the main factors that contribute to the climate change. Global warming occurs when heat trapped in the earth’s atmosphere that caused by excess greenhouse gases such as Carbon Dioxide (CO2), Methane (CH4) and Nitrous Oxide (N2O). All of these gases form a layer in the atmosphere thus reflecting the sun’s ray back down to the earth. The amount of greenhouse gases keep increasing due to the all activities that contribute on it. During the Conpenhagen Climate Change Summit in December 2009, The Malaysia Government stated that Malaysia is committed to do its best in combating climate change. As such, Malaysia will voluntarily slash by up to 40% carbon emission by 2020 compared with the 2005 levels. According to international Energy Agency, 2009, Malaysian’s emission intensity was higher than the global average for the energy sector in 2007. This shows Malaysia is one of the major countries that contribute to global warming.

Power plant is the main contributor to the carbon dioxide (CO2), following by transportation, industry sectors and others. In order to reduce CO2, the government needs to focus on the development of Renewable Energy. There are few potential renewable energy area such as hydro, biomass, and solar. There are a number of hydro power stations in Malaysia peninsular that contribute to the total of 1911 (MW) and few more in Sabah and Sarawak. This contributes to 6.3% of total energy generation in Malaysia. Bakun Dam with the capacity of 2400 MW is under construction and will increase the percentage of hydro energy generation. Solar is another potential renewable energy that available in Malaysia. As a tropical country, Malaysia...
