Renewable electricity is often referred to as the answer to our need to reduce carbon and save the planet from climate change.
But does it?
In UK, we have three main sources of renewables -
- Hydro, which is reliable and can be switched on at times of high demand, and is about 2% of national capacity
- PV, which generates when the sun shines, mainly in summer -and certainly not at 5:30pm in winter when peak demand occurs-
- Wind, which is intermittent and can not be relied upon to generate at peak consumption times.
