Will electric boilers cost more than gas?

Currently, as of April 2025, under the current energy price cap, as decided by Ofgem, electricity costs are 4-5 times higher than gas per kWh. So, despite running at 100% efficiency, an electric boiler will likely still cost more than double compared to a gas boiler, new or old.

How many TWh of electricity storage are there?

Today, an estimated 4.67 TWh of electricity storage exists. This number remains highly uncertain, however, given the lack of comprehensive statistics for renewable energy storage capacity in energy rather than power terms.

Will electricity storage capacity grow by 2030?

With growing demand for electricity storage from stationary and mobile applications, the total stock of electricity storage capacity in energy terms will need to grow from an estimated 4.67 terawatt-hours (TWh) in 2017 to 11.89-15.72 TWh (155-227% higher than in 2017) if the share of renewable energy in the energy system is to be doubled by 2030.
