Most of you, if not all of you, have come across either a large ground based solar farm or onshore wind farm. Some of you may have also come across small-scale solar modules on the rooftops of residential and commercial buildings in the UK. And some fortunate enough to travel away from the UK may have flown over gigantic offshore wind farms.

It is, but impossible, not to have interacted with renewable energy generation assets if living in the UK or Europe. Renewable energy or clean energy has come a long way over the past decade.

In the UK, renewable energy has become a significant contributor to the UK energy framework, contributing over 25% of total generation capacity. We expect this to increase over the coming decade, as more homes adopt solar and battery storage to meet their energy needs.

Though many suppliers offer green energy to the 29 million UK homes, we must acknowledge the early stage leadership of two key green energy suppliers. Both ecotricity and Good Energy, are green energy companies well known for transforming the traditional UK energy sector from fossil fuels, to a more vibrant and environmentally friendly mix of energy sources and suppliers.
