What is Renewable Energy?

renewable energy

Renewable energy consists of energy derived from natural resources that can be replenished within a few decades without exhausting the resources of the planet.

In some form or another, these resources are readily available almost everywhere, and they include wind, sunlight, waves, tides, rain, biomass, and thermal energy stored in the crust of the earth. 

Hydrogen is included in this list when it is created from renewable electricity – this is referred to as green hydrogen or renewable hydrogen. Green energy are inexhaustible as well. In addition, they do little to no damage to the environment or the climate.

On the other hand, fossil fuels, like coal, oil, and natural gas, are finite resources. As a result, the natural resources we use in our daily lives do not replenish as quickly as they are produced through natural processes. 

The extraction and production of fossil fuels are associated with climate-damaging greenhouse gases as well as health-endangering particles, which makes them inevitable to run out sooner or later.

Why is Energy Efficiency Important?

In addition to adopting renewable energy, improving energy efficiency is crucial for achieving sustainability. Energy efficiency measures aim to minimize energy waste and optimize energy consumption, ultimately reducing the overall energy demand. 

By implementing energy-efficient technologies and practices in buildings, transportation, and industry, we can maximize the benefits of geothermal energy and achieve greater energy savings.

solar energy

Solar power is obtained by converting sunlight into electricity using solar panels or through concentrated solar power (CSP) systems. It is an abundant form of energy and can be used even in cloudy or rainy conditions. Earth intercepts solar energy ten thousand times the rate humans consume energy.

In addition to providing electricity, cooling, natural lighting, heating, and fuels, solar technologies can also be used to generate electricity and fuels. During the past decade, solar panels have become less expensive, making them a popular means of generating electricity. 

Depending on the material type used during the manufacturing process, solar panels have a lifespan of about 30 years.

2. Wind

wind energy

Wind power involves harnessing the wind’s kinetic energy to generate electricity. Wind turbines are used to capture the wind’s energy and convert it into usable power. 

The world’s technical capacity for wind power is more than the world electricity production; there is ample opportunity to deploy significant amounts of wind energy throughout most of the planet.

While there are strong winds in most areas, some of the best wind power generator locations are located in remote areas. There is a great deal of potential in wind power that is offshore.

3. Hydroelectric

hydroelectric energy

Hydroelectric power is generated by utilizing the energy of flowing or falling water. It involves the construction of dams to create reservoirs and the use of turbines to convert the water’s kinetic energy into electricity.

As far as renewable sources of energy goes, hydropower is the most common. As a result, it is in danger of being adversely affected by droughts or ecosystem changes caused by climate change that have an impact on rainfall patterns.

Hydropower infrastructure can adversely affect ecosystems as well. In addition to being more environmentally friendly, smaller hydro is particularly best for remote communities. 

4. Geothermal

Geothermal energy

Geothermal energy harnesses the heat generated by the Earth’s core. It involves extracting hot water or steam from underground reservoirs to generate electricity or provide direct heating.

An enhanced geothermal system is a reservoir that is sufficiently hot and permeable without any hydraulic stimulation but is sufficiently hot.

Electricity can be generated from fluids of various temperatures once they reach the surface. It has been over 100 years since hydrothermal reservoirs have been used to generate electricity.

5. Biomass

Biomass energy

Biomass energy is derived from organic matter such as plants, agricultural residues, and forest products. It can be converted into heat, electricity, or fuel through processes like combustion and anaerobic digestion. 

The burning of biomass generates lots of greenhouse gas emissions, however, they are lower than those produced by burning fossils such as coal, oil, and gas. It is important to limit the use of bioenergy, as large-scale plantations of trees and bioenergy plants can contribute to land use and deforestation changes.

Renewable Energy and Climate Change

Sustainable energy plays a vital role in mitigating climate change. The burning of fossil fuels releases carbon dioxide and other greenhouse gases into the atmosphere, contributing to the greenhouse effect and global warming. By transitioning to clean energy, we can significantly reduce these emissions and curb the pace of climate change.
