Solar Energy

Choose the Correct Answer

Correct Answer : Option d

Explanation
Statement 1 is correct: Solar technologies can deliver heat, cooling, natural lighting, electricity, and fuels for a host of applications. Solar technologies convert sunlight into electrical energy either through photovoltaic panels or through mirrors that concentrate solar radiation. Although not all countries are equally endowed with solar energy, a significant contribution to the energy mix from direct solar energy is possible for every country. The cost of manufacturing solar panels has plummeted dramatically in the last decade, making them not only affordable but often the cheapest form of electricity. Solar panels have a lifespan of roughly 30 years, and come in a variety of shades depending on the type of material used in manufacturing.

Statement 2 is correct: Solar energy is the most abundant of all energy resources and can even be harnessed in cloudy weather. The rate at which solar energy is intercepted by the Earth is about 10,000 times greater than the rate at which humankind consumes energy.

Statement 3 is correct: The International Solar Alliance (ISA) is a crucial initiative aimed at promoting the adoption of solar energy in countries that are richly endowed with solar energy resources, specifically those between the Tropics of Cancer and Capricorn. Launched by India and France during the Paris Climate Conference in 2015, it seeks to enhance the use of solar power to address energy needs, reduce reliance on fossil fuels, and combat climate change.
