To increase the use of renewables and decrease the use of fossil fuels we need energy storage.

An affordable heat store can store 17 KwHr of energy in 210 litres of water at a cost 25% that of the cheapest alternative water tank solution. Quiet and efficiently storing energy whenever there is a surplus, and delivering that energy with the minimum of fuss when there is an energy deficit. No expensive rare earth metals are needed, and it is under 10% of the cost of equivalent battery storage. A real game changer, cheap to install in any home, and needing minimal plumbing skills.

In the UK we pay constraint payments to wind farms so they do not to generate electricity. In 2025, constraint payments in the UK are projected to exceed £1.8 billion, a significant increase from £1.5 billion in 2024. These payments, which compensate electricity generators for reducing output due to grid limitations, are driven by the challenges in transporting renewable energy, particularly from wind farms in Scotland, and offshore North Sea wind farms.

Gas power stations are held in reserve just to supply electricity on windless nights and it is this extreamly high cost of gas powered power stations that set the price of electricity
