The phenomenon of increasingly hot temperatures, flooding everywhere, rising sea levels, increasingly polar ice caps melting to other natural phenomena that occur at this time is a very sad condition.
Examples of Green Technology
The issue of global warming is not even once or twice we hear that makes a lot of people around the world to make technologies that are environmentally friendly while having enormous benefits and can prevent damage to nature. At present, there are also many environmentally friendly technological innovations that are useful to prevent increasingly severe natural damage. Indonesia has a group of bright students who have succeeded in turning bacteria into energy-saving lamps. They are students from the Faculty of Fisheries and Marine Sciences, Brawijaya University. This energy-saving pendant lights Sydney lamp can overcome the problem of the energy crisis.
Along with population growth, energy needs are also increasing while the supply of fossil energy-based energy is running low. Reporting from Tempo.co, a group of students took advantage of the bioluminescence bacteria, a unique bacteria in the body of a squid that is able to emit blue light. The light gets brighter if the number of bacteria added. This lamp has the advantage, that it is environmentally friendly and economical. Even this lamp can be used for life because the dead bacteria will produce new broodstock.
EcoATM is a kiosk that functions automatically to buy back used cellphones and MP3 players from users. If we run out of money in the middle of the month, this ATM can be a savior. The machine will analyze the condition of the goods and look for the highest price on the market. If you agree, we can take the money. Then, ecoATM sells it back to other users or is recycled.
This panel of solar cells has long been known for its ability to convert light into electricity because its strongest source comes from sunlight. Solar panels are also often referred to as photovoltaic cells, which means “electric light.” These cells depend on the photovoltaic effect to absorb solar energy so that the current flow between two opposing charged layers. Solar panels are not a new invention, especially in developed countries. But the potential for large energy savings makes the use of solar panels more widespread throughout the world, including Indonesia. For just one installation, we can get energy resources in the long run without leaving waste or pollution.
Wind can be a good alternative energy source to replace fossil fuels. The blades of the wheel will spin and move when there is wind energy pushing them. In addition to replacing fossil fuels, windmills also function as power plants and help channel water in immigration. In terms of the use of environmentally friendly energy, windmills are able to maintain environmental cleanliness, because they do not cause air pollution at all, in contrast to other fuels that can cause air pollution that is harmful to the earth’s atmosphere.
