Alternative Energy: Understanding According to Experts, Characteristics, Benefits, Terms and Types

---

Alternative Energy is a term that refers to all energy sources that can be used which aims to replace conventional fuels without the unintended consequences of p the.

The term “alternative” refers to a technology other than that used on fossil fuels to produce energy.

In addition, the use of alternative energy is carried out to reduce the dependence of a country on a country suppliers of major energy sources such as petroleum, because the longer the supplies of petroleum are getting reduce.

History of the Term Alternative Energy

It cannot be separated from the incident in 1973. At that time there was a global oil crisis and gave rise to new initiatives or ideas to look for renewable or renewable energy sources. In another sense, alternative energy is renewable energy. So that the energy crisis that is feared will not occur.

Since then, the United Nations has formed the UNFCCC or United Nations Framework Convention on Climate Change as an effort to reduce the greenhouse effect and global warming. Until now, the institution has consistently implemented the Millennium Development Goals (MDGs) and Sustainable Development Goals (SDGs) for the realization of environmentally friendly energy.

Most people probably understand that so far the energy used by humans has come from petroleum. This is what is called fossil energy, this energy is a type of energy that cannot be renewed. If it runs out, it will also be destroyed. As a result, humans can no longer live properly as before.

In the midst of the issue of global warming and increasingly scarce fossil energy, alternative energy is present as a savior. Energy from natural sources is considered capable of replacing the function of fossil energy. More interestingly, this environmentally friendly energy is renewable and available without limits from natural sources.

Through the benefits of other energy alternatives, human life will become more comfortable and will no longer rely on fossil energy which is predicted to run out in the future.

This is the importance of renewable energy, a new technology that is more environmentally friendly. At the same time solving the problem of fossil energy. This energy is expected to be able to replace petroleum in the future. Of course, with the development of increasingly advanced technology, the presence of alternative energy is considered to be able to support and meet the needs of human life.

Terms of Alternative Energy

• ---

  Cannot Derived from Fossils

Alternative energy should not come from fossils such as petroleum and coal. If it comes from fossils, one day it will run out and cannot be renewed.

• Renewable

Currently our energy source is in the form of fossil energy sources which have the disadvantage that they are non-renewable and take millions of years to make. Alternative energy must be renewable or renewable to overcome these weaknesses.

• Environmentally friendly

The use of fossil energy so far has caused a lot of environmental pollution through the resulting carbon emissions and can cause global warming. Alternative energy must be environmentally friendly so that it is not harmful to the environment and the people in it.

• Can Be Mass Produced

The human need for energy will increase along with the increase in the world's population. Alternative energy must be mass-produced and continuously to support the increasing human needs.

Advantages of Alternative Energy

• Renewable energy, can be used continuously because it will not run out so there will be no energy scarcity.
• Environmentally friendly because it does not produce waste that is harmful to the environment in the long term, except nuclear.
• This energy source is free because it can be obtained for free, it only requires an initial installation fee.
• The energy that can be produced is very large, the supply is abundant because energy is obtained from nature, so the supply will always be there depending on the location.

---

Lack of Alternative Energy

• It takes a lot of money to use alternative energy.
• It takes high technology and complicated thinking to take advantage of alternative energy.
• Availability also depends on the season. Samples of water will be abundant during the rainy season, but will decrease during the dry season.
• Issues concerning the management policy of natural resources, energy and the environment.
• Scarcity of human resources, skills, and supporting resources.
• Still need imported spare parts so that it wastes production costs.
• Lack of participation of institutions in the development of appropriate technology.

  Biodiesel Energy

Biodiesel energy is an alternative energy derived from plant or animal fat that has been mixed with other fuels or is made purely from fat. Biodiesel energy is environmentally friendly, renewable and can eliminate exhaust emissions.

• Ethanol Energy

Energy Ethanol (ethyl alcohol) is an energy source in the form of alcohol resulting from the fermentation of certain plants, such as wheat or corn.

• Methanol Energy

Energy Methanol (methyl alcohol) is an alcoholic fuel derived from wood. Methanol is either used purely, or it can also be used as a gasoline mixture.

• Biomass Energy

Biomass is a type of energy that comes from living things, such as plants, animal waste and human waste. The process of making this energy is to accommodate the waste with a biomass installation tank, and the gas that comes out of the installation is called biogas.

• Biofeul Energy

Biofuel is all energy derived from vegetable materials such as petroleum, jatropha, corn etc. The process of making biofuel energy is by reacting vegetable oil with methanol and ethanol with a caustic soda catalyst. The results of this process can be used as a fuel called Biofuels (BBN).

• Ocean Wave Energy

Ocean waves can be converted into electricity with the working principle of collecting the energy of sea waves to turn a generator turbine.

• Solar energy

Utilization of sunlight can be increased by using a temperature collector in a place so that it will obtain a higher temperature. In addition, solar energy can also be converted into electrical energy, namely by converting solar energy using solar cells consisting of a series of semiconductor element panels.

• Wind Energy

The Netherlands is a country known for its windmills. In the Netherlands wind is used to pump irrigation water. Wind energy can also be used to generate electricity by using a windmill connected to a generator that can produce electricity (wind turbine).

• Geothermal energy

Thermal energy is a type of energy contained in the earth, usually this energy arises due to volcanic activity. There are 3 main types of sources of geothermal heat, namely natural steam, hot water and hot dry rock.

The use of geothermal heat has been used for electricity generation, hot water can be used for heating, while other sources are currently being researched to be used as alternative energy efficient.

• Hydropower Water Energy

Hydropower energy is energy generated from the power of water. Making this energy by making a river water dam which then uses a water pipe that is directed to the turbine.

This is how it happens in PLTA. Hydropower is very dependent on the availability of water, therefore the construction of hydropower is usually in a reservoir or lake.

• Tidal Energy

Tidal energy is a kind of tidal energy, the working principle of tidal energy is that when the tide is high, seawater with a volume of millions of cubic meters rises to the land.

If a large dam is built on the mainland, the high tide will be collected in a reservoir.

At the mouth of the reservoir, a propeller is installed that rotates according to the direction of the water. Usually used two directions of rotation, namely at high tide and low tide.

• Nuclear energy

Nuclear energy is an energy source that comes from a chain reaction of radioactive materials that occur in a reactor.

The energy produced from this process is enormous, from 1 gram of radioactive substance it can produce 50,000 kWh hours. Nuclear energy also does not emit greenhouse gases and causes global warming.

However, from the many benefits and conveniences obtained, there is a considerable danger, because if a radiation leak occurs it can endanger the environment and human health. Radiation that occurs can cause cancer, hereditary defects to death.

• Piezoelectric Energy

Piezoelectrics are various types of alternative energy that have a working principle in the presence of pressure that is carried out and will be converted into electricity. Piezoelectric is a system that can generate electricity from the conversion of mechanical energy.

• Natural Gas Energy

Natural gas is a gas that collects from underground by having various kinds of hydrocarbon mixtures that have high compressive strength. Once processed, natural gas can be used for cooking like Elpiji.

In addition, natural gas can also be used to fuel motor vehicles and factory machines. Natural gas is also used for power generation (PLTG).
