The main culprit, it is argued, is carbon dioxide, better known as CO2, and its increasing levels in the atmosphere, now at their highest in over half a million years. Could we make better use of this CO2?

There is surprisingly little information and debate on how to electrify our roads. If all cars become electric, how much electricity will be needed, how is it produced and distributed?

SolarCoin is a blockchain-based virtual currency which was initiated by SolarCoin Foundation to speed up the global renewable energy transition.
