However, this claim by the director of PT Transjakarta is somewhat inaccurate, as the fossil fuel energy still covers more than 80% of the energy mix in Indonesia. This is a sad fact, remembering that Indonesia has the target to meet 25% energy mix from renewable energies, where in the end of 2018, it was still only 13% and comes mainly from hydro and geothermal energy.Â
By using electric buses, the emission is only shifted from the combustion of diesel fuel or CNG (compressed natural gas) into the energy conversion in power plants. Moreover, the electricity generation in Indonesia is still dominated by coal power plants (44% according to EnergyPedia in 2018), which impacts the environment more severely than diesel and CNG.Â
From the viral documentary "sexy killers", we know that the coal power plant industry in Indonesia is dominated by powerful people in the government and won't be replaced with a more environmentally-friendly power plant in the near future. Coal doesn't only damage the land through the mining process, but also produces 50%-60% more carbon dioxide than natural gas due to the low C:H ratio of coal.Â
