Have you ever thought about your electrical habits and how you could be destroying the environment with them? Now, Indonesia’s energy situation is not the best. The country’s energy mostly comes from nonrenewable and unsustainable energy sources. Indonesia relies heavily on its main commodity of coal, palm oil and gas as energy. To be precise 80% or 30GW of Indonesia’s total energy. Unfortunately, coal and oil are not renewable sources. Coal and oil will eventually run out, and the gasses they release (fossil fuels) and how they extract them (oil plantations that destroy rainforests and mines that destroy the ground) are bad for the environment. Energy equity does not exist in Indonesia; some places have as much as they want (Java and Bali) and others have electricity for only a few hours a day.
This forces people to use makeshift means of energy such as car batteries, lamp oil and these sources are more unsustainable and even dangerous. Lamp oil can be very flammable, causing much death and destruction. And car batteries only last for so long. When car batteries are thrown away, many people don’t know how to dispose of them correctly, this results in the lush soils being poisoned by the car batteries, killing them. Now the country has started the usage of renewable sources such as geothermal and hydropower. Unfortunately, these energy sources only represent 20% of the total energy (18% hydropower, 2% geothermal). It is quite ridiculous that this situation of using batteries, using nonrenewable sources is still rampant. Indonesia is a blessed country that can hold so many options for renewable sources. It is time to change and switch our power for the betterment of this country.
Now before we enter the renewable and sustainable energy potential of Indonesia and how you can contribute, a big misconception needs to be erased. Hydropower is not sustainable. Just because the words renewable and sustainable appear, that does not necessarily mean good. There are a few misconceptions. Ever thought about what hydropower comes from? Hydropower relies on dams, and it is now obvious that dams are very bad for the environment. Dams stop the natural flow of the river, where the environment depends on the flowing river. Animals living within the dam will all suffer, particularly from drowning. Now for the animals over the dam. Since there is now significantly less water many fish species and
other animals that live in the water would suffocate and have less space to move. Dams also affect the life cycles (ability to have offspring and growing up to adulthood) of both animals living within and over the dam which could lead to their extinction. The dam will also cause soil erosion, where the soils will be deprived of river water and will dry up and crack away. The lush rainforests will be turned into a depressing desert. An active example of the destruction a dam can cause is the Tapanuli orangutan. Already have a small population and being the rarest ape in the world, if a dam called the Batang Toru hydropower plant came into fruition, it will destroy the rainforests and will cause extinction or at least cause more death to the Tapanuli orangutan. Dams won’t just affect the animals but the humans as well. With the soil erosion, the once fertile land will dry up, making growing crops harder. Many people that dedicate their lives as farmers, will lose their jobs and go poor. Settlements living near the river will be destroyed from the flooding caused by the rising waters from the dam holding up most of the water. This will cause homelessness and death to people once living in the settlement. This situation will not help with the already rising poverty of Indonesia. This is not saying hydropower is all bad. Other sources of hydropower such as watermills are good. Instead of stopping the natural flow of the river, it uses the natural flow to power up. The kinetic energy produced by the moving watermill is converted by a generator to electricity. The river gets to flow normally while your electrical appliances can work. This is just to raise awareness on how big dams are bad for the environment.
Now with all of that set and done, this is how you can contribute to the Indonesian energy
situation and environment. Indonesia is a land of possibilities. The variety and potential of
renewable sources that aren’t just hydropower are large. The easiest and most common way to
do it is solar power. Solar power uses the power of the sun. Through solar panels, the sunlight is absorbed and stored. Later at the end of the day where there is no sunlight, the stored sunlight will be converted through solar cells within the panel. These solar cells hold semiconductor wafers that have positive and negative sides. When the cells are charged the electrons (what causes electricity) open and turn into the electric current from the electric field of the wafers. Now you have solar electricity. Solar power is the most accessible and one of the most eco friendly of all renewable sources. What I mean by accessibility is that it can be bought whole, no need for DIY and stuff. Unfortunately, that’s how far that accessibility goes. Solar energy is very expensive in both buying it and setting it up. It does not help that Indonesia is a third world country. Not everyone is rich. But fortunately, It’s the most eco-friendly because you just attach the panels on your roof and done. It does not release any gas and sunlight is eternal. It also fits in with the tropical climate of Indonesia. So if you have the money and start using renewable and sustainable sources, start from that.
Now there is wind energy. Wind energy uses windmills as its power distributor. The wind makes the windmill move, causing kinetic energy (movement energy). The kinetic energy will go through a generator and convert that to electricity. The electricity then usually goes through wires under the ground and goes to your houses. Now wind energy is a more difficult thing to do yourself, as you can’t just buy a big windmill, unlike solar panels, but it’s possible. You can make a homemade windmill, as long as you have a firm material to hold up the wind turbines, the wind turbine is made of something that moves easily in the wind, has good wiring and a strong generator. Wind energy has its downsides. It might not look attractive to some of you and the turbines could hit flying animals. One way to avoid that is to not have a windmill that moves so fast and the windmill is in a low bird concentration location. If you don’t have the time and effort, something as simple as raising awareness and advocating for the use of wind energy is great enough. The next sustainable source is geothermal. Now geothermal energy is energy from the earth’s core. The heat of the earth heats water from reservoirs in the earth and it turns into steam. That steam rotates a turbine which becomes kinetic energy. The kinetic energy enters a generator and it is the electrical energy. It is kind of a hybrid of hydropower and wind power. Very much the better option than hydropower. Now you probably can’t use geothermal energy because it can only happen in volcanoes and that is dangerous. But you can advocate for the use of geothermal energy as many people still don’t know about its existence. Bring out the underrated geothermal and end the reign of the overrated hydropower.
Now the last option for renewable energy in Indonesia is biogas or biomass. Biogas is energy from wastes. These wastes could be animal waste, plant waste or even human waste. They are all put in a biomass machine where the wastes are turned into energy. It is a simple endeavour but it is still very expensive. It is also not for the faint of heart as this is the least hygienic of all the renewable sources.
In conclusion, Indonesia, in terms of its governments, is moving forward. It is said that by 2025, Indonesia will be using 23% of renewable sources. And will move on to renewable sources mostly in 2050. Unfortunately, this renewable source does come by using hydropower from big dams. 2050 is still a long way from 2021. By then it could be already too late. So that is why you need to take action now. Try using these sustainable and renewable sources. Limit the usage of nonrenewable sources of coal, gas and oil (palm oil especially). Or at least bring awareness to it. Indonesia’s energy habits can change, it will be difficult as a nonrenewable source of palm oil is the country’s most prized possession. But it can change, with how diverse the country is, it can change, as long as you contribute and work together for the better.
