What is Renewable Energy? Type, Advantages, Future Prediction & More Facts

Written by Rayden Sam Posted on 2024-01-30

Renewable energy sources include things like biomass, solar power, wind power, and geothermal power, to name a few examples.

About Renewable Energy: Some resources can never be replenished. Some biomass sources are not worthwhile investments. Wind, solar, and hydropower create electricity for the grid, as well as for heating and cooling. Renewable energy sources provide for around 20% of the world’s total energy supply or 30% of total power. The 7 percent consumption of biomass in total has been steadily declining. The energy usage for solar water heating is 4%. Tens of millions of people are employed in photovoltaics.

The usage of renewable energy technologies has increased as they have become more efficient and less expensive. Renewable energy is strongly preferred in new installations. Solar and wind energy are the most cost-effective new energy sources in most countries.

Some countries consume more than half of their energy from renewable sources. Some countries employ renewable energy. Renewable energy markets will expand in the 2020s and beyond.

According to the study’s conclusions, a global transition to 100% renewable energy for electricity, heat, transportation, and desalination is achievable.

In comparison to fossil fuels, renewable energy sources are more extensively distributed. Renewable and efficient energy not only boosts the economy, but it also enhances energy security.

Carbon subsidies harm renewables. Solar and wind power are becoming increasingly popular all around the world.

Renewable Energy-Future Prediction

The International Energy Agency predicted in 2021 that renewables would need to expand at a rate of 12 percent per year through 2030 in order to achieve net zero carbon emissions. Large-scale renewable energy projects are common in developed countries, but they are also well-suited to emerging countries, where energy is often critical to human growth. Electricity can efficiently convey heat or products and is clean at the point of use, which are all advantages of using renewable energy in conjunction with growing electrification.

As an added benefit, electricity reduces greenhouse gas emissions, which are a major source of worry in developing countries. In 2021, China will account for more than half of global renewable energy growth.

Renewable Energy- Mainstream Technology

We can generate electricity and heat by capturing the sun’s energy through concentrated solar power, concentrator photovoltaics (CPV), solar architecture, and artificial photosynthesis. Solar power is the dominant source of new renewable energy.

When it comes to capturing and transmitting solar energy, passive and active systems have significant distinctions. In solar passive design, thermal mass and light dispersion materials, as well as naturally ventilated rooms, can be used.

Solar electrical energy is produced using photovoltaics (PV) and concentrated solar power (CSP), whilst sun thermal energy is produced by using solar collectors to heat water (CSP).

The photoelectric effect is used in photovoltaics to convert light into direct electricity (DC).

Solar PV, except hydropower, is a multibillion-dollar and rapidly increasing business.

Concentrating solar power results in a narrow beam of light (CSP). CSPs became commercially viable in the 1980s. CSP-Stirling generates the most solar power.

Renewable Energy-Policy

The implementation of supportive government policies has been important to the rise of renewable energy sources. While Europe dominated in the early 2000s, most countries now have some sort of energy policy.

Key Points
