Dusseldorf Climate crisis, high energy prices, fear of the gas supply stop – there are currently many reasons to wish for more independence in your own energy supply.
Those who are energy self-sufficient produce their own electricity and heat. High prices and supply bottlenecks then no longer play a role, and ideally the energy sources used are renewable.
