Solar energy facts and statistics 2020
Solar energy is a rapidly growing source of renewable energy, and its importance in the battle against climate change is becoming increasingly apparent. As we enter 2020, it is crucial to take stock of the current facts and statistics surrounding solar energy.
1. Rapid Growth: Solar energy has experienced tremendous growth over the past decade. According to the International Energy Agency (IEA), the world added a record-breaking 97 GW of solar energy capacity in 2019. This represents an increase of 12% compared to the previous year.
2. Increasing Affordability: The cost of solar energy has plummeted in recent years. According to the Solar Energy Industries Association (SEIA), the cost of solar panels has dropped by 70% over the past decade. This decrease in cost, combined with government incentives and tax credits, has made solar energy an increasingly attractive option for homeowners and businesses.
3. Job Creation: The solar energy industry has emerged as a significant source of employment. The U.S. Bureau of Labor Statistics reports that solar installer is currently the fastest-growing occupation in the country. In 2019, the solar industry employed around 250,000 workers in the United States alone.
4. Energy Independence: Solar energy provides an opportunity for countries to reduce their dependence on fossil fuels and importation of energy. By harnessing the power of the sun, countries can generate their own electricity, thereby gaining energy independence and enhancing their energy security.
5. Environmental Benefits: Solar energy is a clean and renewable source of power that produces no greenhouse gas emissions during operation. According to the SEIA, in 2019, solar energy installations in the United States prevented approximately 64 million metric tons of carbon dioxide emissions, equivalent to planting over 1.2 billion trees.
6. Grid Resilience: Solar energy can enhance the resilience of the power grid. Distributed solar energy systems like rooftop solar panels can serve as decentralized energy sources, reducing the vulnerability of the electricity supply to major disruptions and outages.
7. Storage Solutions: The deployment of energy storage systems is increasing in tandem with solar energy installations. Batteries allow for the storage of excess solar energy generated during the day, which can be utilized during the night or during periods of low sunlight. This enhances the reliability and flexibility of solar energy systems.
8. Mega Solar Projects: Large-scale solar projects, commonly known as mega solar, are gaining popularity worldwide. These projects involve the installation of numerous solar panels in a centralized location, such as solar farms or solar parks. These installations can generate a significant amount of electricity to power entire communities or even cities.
9. Developing Countries Embrace Solar Energy: Solar energy adoption is not limited to developed countries. Many developing nations are recognizing the potential of solar energy to provide electricity to remote areas, bypassing the need for costly grid infrastructure. Off-grid solar systems, including solar lanterns and small solar home systems, are transforming the lives of millions of people living in energy poverty.
10. Technological Advancements: Solar energy technology continues to evolve rapidly. Research and development in photovoltaic cells are resulting in increased efficiency and lower costs. Thin film solar panels, concentrated solar power, and new materials such as perovskite are all contributing to the further expansion of solar energy.
In conclusion, solar energy is experiencing unprecedented growth, becoming more affordable, and generating numerous economic and environmental benefits. With its potential to mitigate climate change and enhance energy security, solar energy is poised to play a vital role in our transition to a clean energy future.
