EVERYDAY SCIENCE

Detailed explanation-1: -Passive designs include greenhouses and sun parlours. The sun’s rays penetrate through the glass windows, and the inside of the building receives and absorbs the warmth. Passive solar systems may be built into residences, workplaces, and commercial sites to maximise their benefits.

Detailed explanation-2: -There are two main types of solar energy technologies-photovoltaics (PV) and concentrating solar-thermal power (CSP).

Detailed explanation-3: -Alternative energy here includes hydroelectric energy, solar energy, geothermal energy, wind energy, nuclear energy, and biomass energy. The data come from the World Bank.

Detailed explanation-4: -Most renewable energy is derived directly or indirectly from the sun. Sunlight can be captured directly using solar technologies. The sun’s heat drives winds, whose energy is captured with turbines. Plants also rely on the sun to grow and their stored energy can be utilized for bioenergy.

Detailed explanation-5: -An energy source that is both renewable and inexhaustible by definition. Everywhere gets sunlight. It’s very well suited to batteries and the electricity grid. The sun creates local wealth and jobs. Technological versatility. Minimal maintenance required. Green until the end of life. More items
