There is an energy source that, in just one and a half hours, provides as much energy as we consume in a whole year, which is also free, does not give rise to any local emissions and would give us and the rest of the world’s population better prospects.
If everyone in the world used the sun as an energy source, it would solve many climate problems.
The sun may appear too rarely in some parts of the world, but it is as obvious that it is there behind the clouds as when it is clearly visible against a clear blue sky. From the day we are born to the day we die, through all the stages of life we see the sun go up and down, we turn to it to defrost frozen winter children and we enjoy the warmth it gives hot summer days.
The sun is the prerequisite for us to live on earth – but it is also the solution to humanity’s energy problems. The sun is fifteen million miles away but reaches us in just over eight minutes and our planet is constantly met with energy from the sun. In just one and a half hours, we receive solar radiation, which corresponds to all the energy we consume for a whole year, on the entire globe.
The energy that reaches the earth’s surface every day in the form of sunlight is 8,000 times greater than what humanity wastes in a year. The best part is that the energy is completely free and will continue to flow over us as long as the sun is shining, which is for about 4.5 billion years.
The only problem is that the way we live means that life that we now know will not last as long. In wealthy countries, we live as if there were 4.2 worlds instead of 1 and 2017, the earth’s resources ended on August 2, a date that comes earlier for each year, according to the World Wildlife Fund (WWF).
Until 1987, the earth’s resources were available all year, but since then we have been consuming them at an ever-faster rate. The biggest culprit is carbon dioxide emissions and the use of fossil resources. 75 percent of all the greenhouse gas emissions that warm our planet comes from the use of fossil energy.
