Energy efficiency is about using less energy to do the same job, equally as well or better.
For example LED tubes can replace old fluorescent tube lighting in classrooms creating a more pleasant light that turns on instantly, doesn't flicker, lasts longer and uses about half the amount of energy. This saves a lot of money over time, creates less of the greenhouse gas emissions that cause Global Warming and Climate Change, and reduces the need to build more power stations.
Energy efficiency practices like increased insulation in buildings and more efficient heating, creates warmer, drier and healthier homes and schools.
Energy efficiency has very positive health, social, and economic benefits.
