The Future of Renewable Energy: What’s Coming Next?

Renewable energy has emerged as an essential aspect of the world’s energy mix. Renewable energy sources such as wind, solar, hydro, and geothermal have become increasingly important in meeting the world’s energy needs. Renewable energy is seen as the future of energy production, especially with concerns about climate change, energy security, and sustainability. This article will examine the latest developments in renewable energy and explore what’s coming next.

The Current State of Renewable Energy

The renewable energy sector has made significant strides in recent years. According to the International Energy Agency (IEA), renewables accounted for nearly 28% of global electricity generation in 2020. This was an increase from 26% in 2018. Wind and solar power have become the leading sources of renewable energy, accounting for almost 80% of the total electricity generated from renewable sources.

Advancements in Solar Energy

Solar energy has become a popular choice for many households and businesses. With advancements in technology, the efficiency of solar panels has increased, and the cost has decreased. According to a report by the IEA, solar power is now the cheapest source of electricity in history. In December 2020, a new record was set when a solar project in Abu Dhabi produced electricity at a cost of just 1.35 cents per kilowatt-hour (kWh). This is significantly cheaper than coal, which averages around 5 cents per kWh.

Innovations in Wind Energy

Wind energy has also made significant strides in recent years. Advances in technology have increased the efficiency of wind turbines, making them more cost-effective. Offshore wind farms have become increasingly popular, with the first floating wind farm launched off the coast of Scotland in 2017. According to the IEA, offshore wind is expected to become a $1 trillion industry by 2040.

Hydro Power

Hydropower has been in use for centuries and remains an important source of renewable energy. Hydroelectric power plants generate electricity by harnessing the energy of falling water. Scientists are now exploring new ways to make hydro power more efficient and cost-effective. For example, a new type of turbine developed by scientists at Oxford University can generate electricity from low-velocity water sources such as canals and slow-moving rivers.

Geothermal Energy

Geothermal energy is another renewable resource that has gained popularity in recent years. It involves harnessing the natural heat of the earth’s core to generate electricity. According to the International Renewable Energy Agency (IRENA), geothermal energy has the potential to provide up to 10% of the world’s electricity needs.

New Developments

Despite the progress made in renewable energy, there is still much room for improvement. Scientists and engineers are working on new technologies that will make renewable energy more efficient and cost-effective. Here are some of the latest developments in renewable energy:

  • Solar Cells That Can Generate Electricity from Rain: Researchers at the City University of Hong Kong have developed a solar cell that can generate electricity from rain. The cell is coated with a thin layer of graphene, which allows it to generate a small current when it comes into contact with raindrops. This technology could be particularly useful in regions with high rainfall.
  • The Development of New Heating Systems: Researchers at the University of Cambridge are developing a new type of heating system that could revolutionize the way we heat our homes. The system uses hydrogen as a fuel and generates electricity as a byproduct. This technology could significantly reduce carbon emissions from heating.
  • The Emergence of Small-Scale Electric Generators: Scientists are developing small-scale electric generators that can be used to power individual homes and businesses. These generators can be powered by a variety of renewable energy sources, including wind and solar power.


Renewable energy is the key to a sustainable and clean energy future. As we have seen, significant progress has been made in the renewable energy sector, with solar and wind power leading the way. However, there is still much to be done to make renewable energy more efficient, cost-effective, and accessible.

The latest developments in renewable energy, such as solar cells that generate electricity from rain and new heating systems, show promise in taking renewable energy to the next level. As more resources are invested in renewable energy, we can expect to see even more innovative technologies and advancements in the sector.

It is clear that the future of energy lies in renewable resources, and countries around the world are increasingly recognizing this fact. Governments, businesses, and individuals must work together to accelerate the transition to renewable energy and ensure a sustainable and clean energy future for generations to come.

The development of renewable energy is a crucial aspect of addressing the pressing global challenges of climate change, energy security, and sustainability. The latest technological advancements in solar, wind, hydro, geothermal, and other renewable resources show great promise for a brighter and cleaner energy future. As the world continues to prioritize renewable energy, we can expect to see even more exciting innovations in the years to come.
