Why do we need energy and list three type of energy

Energy is something very important to people. It helps to light our homes, dry our clothes, and even cook our food. If we didn't have energy I don't know where we'd be. Three types of energy are: Solar Energy, Wind Energy, and Hydro Energy.

We need energy because without it we won't be the same. Infact, we won't be alive today. We use energy for everyday things and well, for everything.

Explanation:

3 types of energys are Electric, Atomic and Mechanical.

WOW thank you for 42 points c:

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
