Why do green plants need solar energy
Solar Energy
Solar energy is a form of renewable energy, in which sunlight is turned into electricity, heat, or other forms of energy we can use is a "carbon-free" energy source that, once built, produces none of the greenhouse gas emissions that are driving climate change. Solar is the fastest-growing energy source in the world, adding 270 terawatt-hours of new electricity
Why did renewables become so cheap so fast?
Look at the change in solar and wind energy in recent years. Just 10 years ago it wasn''t even close: it was much cheaper to build a new power plant that burns fossil fuels than to build a new solar photovoltaic (PV) or wind plant. Wind was 22%, and solar 223% more expensive than coal. But in the last few years this has changed entirely.
How Plants Harness Solar Energy

What is Photosynthesis
Through the transfer of energy from the Sun to plants, plants build sugars that humans consume to drive our daily activities. Even when we eat things like chicken or fish, we are transferring energy from the Sun into our bodies because, at some point, one organism consumed a photosynthetic organism (e.g., the fish ate algae).
