Sustainable use and management of nutrients is an important issue for food, energy and water systems.

The increase in population coupled with rising per capita income and associated change in consumption habits will put unprecedented stress on food, energy and water (FEW) resources.

Scottish farmers have been using clean energy technology normally used by buses and bin lorries to power their farm machines, helping to reduce emissions and make efficiencies. This helps to advance both goal 7 and goal 12.
All-Energy 2018
All-Energy, the UK’s largest renewable energy and low carbon event, is taking place on 2nd & 3rd of May 2018 in Glasgow; it brings together the UK’s largest group of buyers across the value chain, including investors, project developers, end users and policy makers, among others. Showcasing the complete range of renewable and sustainable technologies and with a world-class free-to-attend conference alongside, All-Energy brings together over 7,500 supply chain and business energy end users – including the largest group of renewable energy developers and supply chain partners seen anywhere in the UK.

Sang, Yuanrui; Karayaka, Hayrettin Bora;  Yan, Yanjun; Yilmaz, Nadir; Souders, David. 1.18 "Ocean (Marine) Energy", Editor: Ibrahim Dincer, Comprehensive Energy Systems, Elsevier (2018), Pages 733-769, ISBN: 9780128149256.

Marine energies are still early in their development and their potential is largely untapped, but our oceans could supply the entire world with power and begin to eradicate our dependency on fossil fuels. As scientists and governments further research and develop marine energy, we can expect (and hope) that it will become a significant global energy source in the next decade. This book chapter advances SDGs 7, 11 and 13.
This book chapter addresses SDG 7 by explaining how geothermal energy can help fulfill energy transition needs and what the future holds for this energy source.
