speech on 'Energy Sources for sustainability '
Answers
HEY! Sustainability is determined by three different parameters: environmental sustainability, social sustainability and economic sustainability. these are the three main aspects which make an energy source sustainable. HOPE IT HELPS :)
Sustainable energy is a form of energy that meets our today’s demand of energy without putting them in danger of getting expired or depleted and can be used over and over again. Sustainable energy should be widely encouraged as it does not cause any harm to the environment and is available widely free of cost. All renewable energy sources like solar, wind, geothermal, hydropower and ocean energy are sustainable as they are stable and available in plenty.
Sun will continue to provide sunlight till we all are here on earth, heat caused by the sun will continue to produce winds, the earth will continue to produce heat from inside and will not cool down anytime soon, movement of earth, sun and moon will not stop, and this will keep on producing tides.
