A Renewable Energy Law in the Philippines?

For the last 13 years, the environmentally conscious have struggled to push for a renewable energy law in the country. Without the law, it is more economically viable to put up coal fired power plants because of the higher taxes imposed on renewables. The Philippines is the 2nd largest producer of geothermal steam in the world ( 2nd to the US). Wind potential is valued at about 7GW, roughly enough to power 30,000 homes. There's a lot of sun, rivers and ocean to be tapped. Why hasn't our government been really keen on getting this set-up? Is there a powerful coal lobby that hinders us? After 13 years, the renewable energy bill is finally in the Philippine senate. In the closing days of this congress, when a certified urgent bill such as this is calendared...guess what...the Honorable Chair of the Senate Energy Committee, Miriam Defensor Santiago, doesn't show up!!! Why???
