The global energy demand is predicted to grow more than 50% by 2025, inducing possible adverse effects on climate due to increasing atmospheric CO2, a greenhouse gas, from fossil fuel burning. This issue can be solved by replacing fossil fuels by renewable fuels such as trees. The use of trees such as poplar, eucalyptus, salix, paulownia (photo), and black locust has many advantages such as allowing multiple harvests, revitalizing local economies, promoting energy self-sufficiency, and reducing environmental problems. Scientists Durán et al. show the benefits of short-rotation tree plantations for the bioenergy sector.
