What is considered clean energy? Clean energy is energy that comes from renewable, zero emission sources that do not pollute the atmosphere when used, as well as energy saved by energy efficiency measures. There is a degree of crossover between clean energy and green or renewable energy sources, but they are not exactly the same.
What is the safest clean energy? Nuclear energy, for example, results in 99.9% fewer deaths than brown coal; 99.8% fewer than coal; 99.7% fewer than oil; and 97.6% fewer than gas. Wind and solar are just as safe.
Why is clean energy considered to be important? Using more renewable energy can lower the prices of and demand for natural gas and coal by increasing competition and diversifying our energy supplies. And an increased reliance on renewable energy can help protect consumers when fossil fuel prices spike.
Is it cheaper to switch to clean energy? According to the findings of climate analytics firm TransitionZero, it is now cheaper to switch from coal to clean energy, compared to switching from coal to gas — thanks to the falling cost of renewables and battery storage, coupled with the rising volatility of gas prices.
