Ans. While renewable energy has numerous benefits, there are challenges in scaling up its deployment. One challenge is the intermittency of certain renewable energy sources, such as solar and wind power, which depend on weather conditions. This requires the development of efficient energy storage systems to ensure a continuous and reliable power supply. Additionally, the initial investment and infrastructure requirements for renewable energy projects can be costly. However, as technology advances and economies of scale are achieved, the costs are gradually decreasing. Government policies and regulations also play a crucial role in incentivizing renewable energy deployment and overcoming barriers to its widespread adoption.
