One regional report and five country reports The Power Sector <strong>Vision</strong> has been sub-divided in different separate documents. There is a report for each of the countries and one regional report. The regional report presents a summary of the national reports, and discusses regional power sector topics such as grid interconnection. Defining renewable energy, energy efficiency and sustainable energy “Renewable energy” is derived from natural processes that are replenished constantly. In its various forms, it derives directly or indirectly from the sun, or from heat generated deep within the earth. Included in the definition is energy generated from solar, wind, biomass, geothermal,hydropower and ocean resources, and biofuels and hydrogen derived from renewable resources” (IEA, n.d.). “Energy efficiency is a way of managing and restraining the growth in energy consumption. Something is more energy efficient if it delivers more services for the same energy input, or the same services for less energy input.” For instance, when a LED uses less energy than an incandescent bulb to produce the same amount of light, the LED is more energy efficient” (IEA, 2016). “Renewable” does not necessarily mean “sustainable”. The location, design, planning, development, construction and operation of power plants and their energy sources (e.g. biomass) will have a strong impact on the sustainability of the project. Special additional caution is recommended for hydropower and biomass projects, which can have severe social and environmental impacts. Initiatives exist to improve the sustainability of these energy sources. Among those, the World Commission on Dams (WCD) gave enormous learning on hydropower which remains relevant; building on the WCD principles the Hydropower Sustainability Assessment Protocol is a tool that promotes and guides more sustainable hydropower projects 1 ; the Roundtable on Sustainable Biomaterials 2 is an independent and global multi-stakeholder coalition which works to promote the sustainability of biomaterials. Their certification system is based on sustainability standards encompassing environmental, social and economic principles and criteria. It is, however, important to remember that such sustainability schemes will not prevent all negative impacts. Seeking to maximise the use of lower impact renewables, such as wind, solar, or geothermal energy, and reducing usage through energy efficiency, remains a priority. 1 http://www.hydrosustainability.org/ 7 2 http://rsb.org/
