Octopus Energy has launched a 'Zero Bills' scheme in a Scottish city, which is part of a broader trend of increasing adoption of net zero technologies such as solar panels and heat pumps in Scotland. The initiative is one of several efforts to reduce energy bills, with the government also planning to make 'plug-in solar' available and launching a Warm Homes Plan. Other energy providers, including EDF and E.on, are also exploring similar tariff options, with some targeting affordable housing and landlords.
