Solar Energy
Solar energy has been growing in popularity for years now and its being used more than ever before. One of the biggest trends in solar energy for 2021 is the use of solar panels for home and business owners who are looking to save money and reduce their carbon footprint. Governments and utility companies around the world are also incentivizing solar energy use by offering rebates and tax credits to those who invest in solar technology for their homes and businesses. This trend is set to continue as more people continue to see the benefits of solar energy.
Wind Energy
Wind energy is also seeing huge growth in popularity and investment. In fact, wind power is now the second-largest source of new power generation globally after solar. Several countries, such as Denmark and Germany, are transitioning to wind power as their primary source of electricity. As technology improves, offshore wind farms are becoming more common, providing a reliable source of renewable energy. In 2021, one trend to watch in wind energy is the use of artificial intelligence to optimize wind power production and lower the cost of energy.
Energy Storage
Energy storage has become a critical part of the transition to green energy. With renewables like solar and wind dependent on the weather, the ability to store excess energy for use on demand is essential. In 2021, the trend in energy storage is towards batteries with longer lifetimes, higher charge and discharge rates, and lower costs. Lithium-ion batteries are currently the most popular form of energy storage, but new technologies, such as flow and solid-state batteries, are set to disrupt the market in the coming years.
Hydrogen Fuel Cells
Hydrogen fuel cells are fast becoming a viable alternative to fossil fuels. Hydrogen fuel cells work by converting hydrogen into electricity, emitting only water and heat as byproducts. This technology has been around for decades but is now seeing renewed interest as a way to power everything from cars and trucks to homes and businesses. Hydrogen fuel cells are particularly useful when it comes to heavy-duty transportation as they offer a range and payload capacity comparable to diesel engines but with zero emissions. In 2021, the trend in hydrogen fuel cells is towards commercialization and mass production, with several automakers expected to release hydrogen fuel cell-powered vehicles.
Green Hydrogen
Green hydrogen is hydrogen that is produced from renewable energy sources, such as wind or solar power. Green hydrogen can be used as a fuel source for power generation, transportation, and industrial processes. In 2021, the trend in green hydrogen is towards scaling up production and reducing the cost of production. As more renewable energy is brought onto the grid, the demand for green hydrogen is expected to grow, making it a critical part of the transition to a greener economy.
Overall, the trends in green energy for 2021 are towards continued growth and investment in renewable energy sources and technology. While these trends are positive, there is still a long way to go before the world reaches a truly sustainable energy mix. Want to deepen your knowledge on the subject?
