Jakten på nya, miljövänliga energikällor (2018)

Everything living on earth depends on energy. The sun is the earth's first and largest source of energy, but to cover the growing need for energy, we have extracted energy from coal, oil, gas, and nuclear power. But it has happened at the expense of the environment. New, cleaner energy sources now need to be developed. Research is underway around Sweden to find new solutions. It's about everything from specially designed molecules, unique nanomaterials, new smart solar cells to artificial photosynthesis.
