The energy source used mostly comes from fossils. The electricity consumed currently consumes 60,163 MW with detailed coal of 29,845 MW, EBT (renewable energy) of 7,260 MW. A gas of 16,779 MW and BBM of 6,279 MW.
Based on DJEBTKE ESDM 2017 data the target for renewable energy power plants is 23% in 2025, but in the challenge in 2017 the energy produced is still far from supported, whereas to add a target it takes 7 years which for 7 years must reach 10% of total energy targeted, whereas EBT increases every year by 0.5% from the previous amount.
The causes of the resulting EBT exceeded the expected target, namely the bureaucracy that had to be passed through was complicated, the lack of clarity of government regulations, both required investors were reluctant to invest in this field.
PLTB or wind power plants use wind as a source of energy, the wind itself exists because the sun’s armpits radiate heat throughout the earth which is not the same for each region, this heat difference results in differences
pressure, this pressure difference is released in the air mass transfer known as wind where the greater the difference in air pressure the greater the wind speed. 1-2% of the sun’s energy received by the earth is converted to wind.
The Indonesian wind energy project has two scales, namely macro and micro. At the macro scale, it produces a large amount of power, unfortunately, the investment costs are expensive and the installation is sufficient
difficult, other than that the turbine used is quite high (above 10 m), whereas at the micro-scale it has a height of 4 -5 m with a power generation of 500 watts for one turbine, also this turbine has a tail that can direct the turbine head to step towards the coming wind.
