🌿 Clean (깨끗한 에너지)

•We think solar energy is cleaner than other energies.

•Wind energy is the cleanest because it doesn’t make smoke.

Hydroenergy is clean because it uses water, not gas or coal.

💰 Cheap (저렴한 에너지)

•We think coal energy is cheaper than solar or wind energy.

•Oil energy is cheap now, but it can be expensive later.

•Solar energy is not cheap, but it is good for the Earth.

🦺 Safe (안전한 에너지)

•We think wind energy is safer than coal or oil.

•Solar energy is safe because it doesn’t make fire or smoke.

⚙️ Easy to Use (사용이 쉬운 에너지)

•We think gas energy is easier to use than other energies.

•Coal energy is easy to use, but bad for the environment.

•Solar energy is not easy to use everywhere, but it’s good for the future.
