Spending of petroleum increased quantity turns to apply other fuels instead. The first energy is solar energy. In general, Thailand is tropical ,there is sunlight throughout the year. Only some people know that the sun gives enormous energy to the world, which can be used to solar cell, that country gets the intensity of the radiation daily average of about 4.7 kilowatt - hour per square meter. It probably can be applied to generate electricity as well. So, there is the most of installation and construction of solar power plant and solar rooftop in the central region and the Northeast. The second energy is geothermal energy. This thermal energy is contained in the rock and fluids beneath Earth's crust. It can be found from shallow ground to several miles below the surface, which can be used by the transport pipeline. Nonetheless, it is also much less popular while it is pure energy from underground directly. The last energy is bioenergetics which process of fermentation and transformation plants or garbage until gases. It is the original power, which is still widely used in rural. In addition, renewable energy is a clean energy available local and no environmental impact. Therefore, we should adopt renewable energy instead or reduce of petroleum.
