An REC can be obtained by supporting renewable energy projects. Carbon offsets can be obtained by investing in projects that remove carbon from the atmosphere or avoid future emissions. Using renewables in the first instance is better than relying on RECs/offsets due to the uncertainty of the effectiveness of such investments. Maximum bonus: 15 points.
