Which of the following is a renewable energy source?

Solar energy is considered a renewable energy source because it is derived from the sun, which is a natural and inexhaustible resource. The sun produces energy that can be harnessed using technologies such as solar panels, which convert sunlight into electricity. As long as the sun is shining, solar energy can be captured and utilized without depleting its availability.

In contrast, natural gas, coal, and nuclear energy are not renewable sources. Natural gas and coal are fossil fuels formed from ancient organic materials that, once consumed, cannot be replenished on a human timescale. They contribute to pollution and greenhouse gas emissions, particularly when burned for energy. Nuclear energy, while not a fossil fuel and capable of generating a significant amount of power with low direct emissions, relies on finite resources like uranium, which can become depleted. Therefore, the sustainable nature of solar energy makes it a key player in the transition to a more renewable and environmentally-friendly energy system.
