Renewable energy is a hot topic in the power generation sector. With increasing awareness of the urgency of the climate crisis, government, industry, and society are feeling the need to diversify energy sources. Though renewables currently account for less than 16% of world energy requirements, the sector is expanding. The good news is that electricity generation from renewable sources doesn’t deplete the natural environment. That doesn’t mean there aren’t some disadvantages to renewable energy. Reliability of supply, storage issues, location and installation costs are all challenges that must be considered.
