It is difficult to predict exactly how much solar energy will be used in 2050, as it will depend on a variety of factors such as technological advancements, government policies, and economic conditions. However, it is likely that solar energy will play a significant role in the global energy mix in the coming decades, as it is a clean and renewable source of electricity.
There are many efforts underway to increase the use of solar energy, including the development of more efficient solar panels, the expansion of solar power plants, and the adoption of solar energy by individuals and businesses. In addition, the cost of solar energy has been steadily decreasing over the years, making it more accessible and financially viable for a wider range of users.
Overall, it is expected that solar energy will continue to grow in popularity and importance in the coming years, and it could potentially play a major role in helping to mitigate the effects of climate change.
