The rise of renewable energy is being driven by a combination of technological advances and the desire for cleaner, more sustainable forms of energy. Renewables are now a mainstream source of electricity and, as a result, many countries are looking to accelerate their transition away from fossil fuels.

One factor driving the growth of renewable energy is cost. The cost of renewables, particularly solar and wind, has plummeted in recent years, making them more competitive with fossil fuels. In some regions, renewables are now cheaper than fossil fuels, even without subsidies. This has led to a surge in investment, particularly in solar and wind projects.

Another driver of renewable energy growth is policy. Many countries have introduced policies and regulations that incentivize the development of renewable energy. Examples include feed-in tariffs, which guarantee a fixed price for renewable energy, and renewable portfolio standards, which require utilities to generate a certain percentage of their electricity from renewables.

Investment in renewable energy has been growing steadily for years and is expected to continue to grow. The International Energy Agency (IEA) predicts that renewable energy will account for 90% of the global power sector's growth by 2025. The COVID-19 pandemic has had an impact on renewable energy investment in the short term, but many experts believe that it will not significantly slow the long-term growth of renewables.

While there are challenges to the continued growth of renewable energy, such as the need for more investment in storage technology and grid infrastructure, the overall trend is positive. As more and more countries commit to transitioning to renewables, it becomes increasingly likely that a future powered entirely by clean, sustainable energy is within reach.
