Last year saw the highest-ever investment in renewable energy generation in Germany, totaling 36.6 billion euros. This value was not only 2.5 times higher than two years prior but also 30 percent higher than the previous record set in 2011. This information comes from a report released by the German Environment Agency on Friday. Nearly half of these investments were allocated to solar installations, surpassing expansion targets significantly. In second place, accounting for 24 percent, was environmental heat, with the majority attributed to the installation of heat pumps. Wind power, which fell short of expansion plans, accounted for just under 20 percent of investments.
