What is Energy Independence?
Reducing reliance on grid electricity by generating your own power from solar panels and storing it in batteries.
Quick Answer
UK homeowners can achieve 50–70% energy independence with solar panels alone, rising to 70–90% with battery storage. Complete independence is impractical in the UK due to short winter days, but significant independence is achievable. The combination of solar PV, a battery, a smart meter, and an EV charger can dramatically reduce a household's reliance on imported electricity.

Energy Independence Explained
Energy independence refers to the ability to generate and consume your own electricity without relying on the public grid. In the residential context, it typically means using solar panels and batteries to produce and store electricity for your home. Full energy independence (going completely off-grid) is rare and expensive, but partial independence — covering 60–90% of your needs with solar — is increasingly achievable and cost-effective.

Frequently Asked Questions
Can I be energy independent in the UK?
Partial energy independence (70–90%) is achievable with solar + battery. Full independence is impractical due to the UK's winter. Most homeowners aim for 60–80% self-sufficiency.
