Renewable energy can provide a host of benefi ts to society. In addition to the reduction of carbon dioxide (CO2) emissions, governments have enacted renewable energy (RE) policies to meet a number of objectives including the creation of local environmental and health benefi ts; facilitation of energy access, particularly for rural areas; advancement of energy security goals by […]
Renewable energy (RE) has the potential to play an important and increasing role in achieving ambitious climate mitigation targets. Many RE technologies are increasingly becoming market competitive, although some innovative RE technologies are not yet mature, economic alternatives to non-RE technologies. However, assessing the future role of RE requires not only consideration of the cost and performance of […]
Historically, economic development has been strongly correlated with increasing energy use and growth of greenhouse gas (GHG) emissions. Renewable energy (RE) can help decouple that correlation, contributing to sustainable development (SD). In addition, RE offers the opportunity to improve access to modern energy services for the poorest members of society, which is crucial for the achievement of any […]
In many countries, suffi cient RE resources are available for system integration to meet a major share of energy demands, either by direct input to end-use sectors or indirectly through present and future energy supply systems and energy carriers, whether for large or small communities in Organisation for Economic Co-operation and Development (OECD) or non-OECD countries. At the […]
Wind energy offers signifi cant potential for near-term (2020) and long-term (2050) greenhouse gas (GHG) emissions reductions. A number of different wind energy technologies are available across a range of applications, but the primary use of wind energy of relevance to climate change mitigation is to generate electricity from larger, grid-connected wind turbines, deployed either on- or offshore. […]
Ocean energy offers the potential for long-term carbon emissions reduction but is unlikely to make a significant short term contribution before 2020 due to its nascent stage of development. In 2009, additionally installed ocean capacity was less than 10 MW worldwide, yielding a cumulative installed capacity of approximately 300 MW by the end of 2009. All ocean energy […]
Hydropower offers signifi cant potential for carbon emissions reductions. The installed capacity of hydropower by the end of 2008 contributed 16% of worldwide electricity supply, and hydropower remains the largest source of renewable energy in the electricity sector. On a global basis, the technical potential for hydropower is unlikely to constrain further deployment in the near to medium […]
Geothermal energy has the potential to provide long-term, secure base-load energy and greenhouse gas (GHG) emissions reductions. Accessible geothermal energy from the Earth’s interior supplies heat for direct use and to generate electric energy. Climate change is not expected to have any major impacts on the effectiveness of geothermal energy utilization, but the widespread deployment of geothermal energy […]
Solar energy is abundant and offers signifi cant potential for near-term (2020) and long-term (2050) climate change mitigation.There are a wide variety of solar technologies of varying maturities that can, in most regions of the world, contribute to a suite of energy services. Even though solar energy generation still only represents a small fraction of total […]
Bioenergy is embedded in complex ways in global biomass systems for food, fodder and fi bre production and for forest products; in wastes and residue management; and in the everyday living of the developing countries’ poor. Bioenergy includes different sets of technologies for applications in various sectors. [gview file=”https://info.aea-al.org/wp-content/uploads/2014/07/Ch2-Bioenergy.pdf” save=”1″]
