What does it mean?

In simple words, the earth is now (2020) 1 degree hotter than it was in the 20th century before our factories started ridiculously emitting greenhouse gasses into the air.

If it doesn’t seem this bad, then you need to think twice.

It only took 4 degrees increase to end the ice age 12,000 years ago.

The damage we have done to the earth is irreversible, so our goal now is to survive by keeping the temperature below 2 degrees which is very possible according to the 2 degrees institute.

If we all switched to solar lights we will reduce the loads on power stations, and as a result, power stations will produce less electricity, which will highly reduce air pollution and greenhouse gases emissions.

  4. 1 bulb electricity cost per month = 6 kW * 13.31 = 0.7986 ≃ 0.8 dollar a month, that’s $9.6 a year and $28.8 for 3 years.
  5. A good quality Solar light bulb costs around $25 and can work for up to 8 years, however, let’s reassume it will only last 3 years.
  6. So after all, you don’t only help the environment, but you also save $3.3 for every light you replace in your home, that’s great HUH!
