In light of increasing energy prices, a low income combined with low energy efficiency can quickly lead to ‘energy poverty’. One way to counteract energy poverty is thus to improve energy efficiency in low income households. In this connection, measures to increase energy efficiency not only mean financial saving opportunities, but also help to meet the growing demand to reduce CO2 emissions. Low-income households are often disadvantaged in two respects: First, knowledge is frequently lacking concerning how consumers can enhance energy savings on a daily basis; and secondly, the financial means are lacking for implementing energy saving tips, e.g. through the purchase of more energy efficient household appliances. Measures which address both issues – knowledge transfer and financial support – can therefore contribute to reducing energy costs in private households.
