The Energy Transition: What You Need to Know

Sustainable energy should be cheap when it's oversupply and more expensive in winter. But renewable energy simply doesn't have the same price regardless of day or night, says Andrew Keen. Energy attribute certificates were developed 20 years ago but haven't moved with the times according to Keen. They tell you where the energy's come from, but they're missing a timestamp telling you when that unit of energy was generated. And so if you use 10 megawatt hours, 10 units of energy in a year and you buy 10 certificates, as long as those certificates were produced in the same 12 month windows when you consume the energy, you're actually allowed to claim to be 100% renewableEnergy.
