Renewable Energy to Fight the Climate Change

, ()

Climate change is becoming more likely due to rising greenhouse gas emissions, global warming, and the usage of non-environmentally friendly power generation materials such as coal. How often do you hear about renewable energy? Isn’t it already well-known to us? Renewable energy is expected to be a viable option for lowering carbon emissions and greenhouse gas emissions. So, what sorts of renewable energy are there?

Wind Power

Wind energy can be converted into electrical energy through the power generation (PLTB) system, by turning a turbine or windmill that can drive a generator to produce electricity. For example, PLTB Sidrap. Other countries that are also developing renewable energy from wind include England, the Netherlands, and Scotland.

Water-based Energy

The conservation process of the kinetic energy of the flow of water into electrical energy is arranged in a hydroelectric power system (PLTA), by utilizing flowing water to turn a pinwheel to drive a generator so that it can produce electricity. Some of the countries that use this energy are the United States (Grand Coulee hydropower), Brazil (Tucurui hydropower), Paraguay & Brazil cooperation (Itaipu hydropower), Venezuela (Guri hydropower), and China (Three Gorges hydropower).

Solar Power

Solar energy is a renewable energy source with a huge and abundant supply, most frequently in the form of solar panels, a technology that converts sunlight into electricity. Germany, the United States, Italy, Australia, and Japan are some of the countries that use the world’s largest solar panels.

Bio-energy

It is a sort of renewable energy that is generated from organic materials that have chemical sun energy. Biodiesel, biovatur, and other materials are created from bioenergy. Indonesia is one of the countries that produce crude palm oil, which is commonly used in biodiesel. There are also other additional sorts of renewable energy:

Other renewable energy sources include ocean wave energy, geothermal energy, tidal energy, current energy, and/or ocean heat. What effect does renewable energy have? What role could renewable energy play in reducing the effects of climate change?

Renewable energy and energy efficiency offer a secure, predictable, and cost-effective approach to achieve massive decarbonization while keeping global warming “far below 2 degrees Celsius.”
According to an IRENA (International Renewable Energy Agency) analysis, a combination of renewable energy, energy efficiency, and increased electrification might achieve the necessary 90 percent reduction in energy-related emissions.

Here are some of the benefits of renewable energy:

  1. A Healthier Environment, The increase of greenhouse gases in the atmosphere is well recognized to be caused by the burning of fossil fuels. There will be a reduction in greenhouse gas emissions when production transitions to renewable energy.
  2. Improved Air Quality, Air pollution rises in tandem with the development of industrial locations. Air pollution has also been exacerbated by the dense population’s use of private vehicles that run on gasoline that isn’t environmentally acceptable yet. Unfortunately, deforestation has exacerbated air pollution by reducing the number of trees that can absorb CO2 and create oxygen. We no longer need to cut down trees to acquire fossil fuels due to the implementation of renewable energy. In deforested areas, we can plant new trees and enhance air quality by increasing the number of trees.
  3. Improving Public Health, Coal and crude oil, for example, have been determined to be hazardous to human health. This is related to the harvesting and burning processes, which are dangerous to humans, contaminate water bodies and pollute the atmosphere. Renewable energy has a better handle on limiting unpleasant consequences.
  4. Natural Habitat Preservation,  Due to human activities, the fuel extraction process has an impact on natural ecosystems, resulting in the displacement of native habitat species and the disruption of fish migration patterns. This hastens the extinction of species that can only exist in their native environment. Renewable energy production is far more environmentally friendly. For example, the Environmental Protection Agency in the United States carefully evaluates land usage for prospective renewable energy production (Giebel, 2016).
This blog series is part of Act Global Project called Act Now on Climate Change. We will be portraying how climate change is affecting us and what is need to do to prevent it from worsening.  Act Now!
