Ocean Thermal Energy Conversion (OTEC)
The total energy available using OTEC systems is one or two orders of magnitude higher than other ocean energy options such as wave power, but the small size of the temperature difference makes energy extraction difficult and expensive. Hence, existing OTEC systems have an overall efficiency of only 1% to 3%. A unique feature of […]
The Geothermal Energy Report – Direct Use and Power Generation Edition 2 – 2005
Geothermal energy is contained in the heated rocks and fluid that fill the fractures and pores within the earth’s crust. It can be harvested in two ways, direct use of hot water or steam for space heating or industrial use such as aquaculture, thermal baths and hot springs, and to power electricity generation plants. Direct […]
Overview of World Generating Capacity in 2007 – Historical Series
Global generating capacity rose from approximately 180 GW in 1938, to 212 GW immediately following the end of the Second World War, and then to 4,519 GW in 2007. Global capacity is forecast to reach 5,955 GW in 2020. Two regions which enjoyed the fastest rates of growth in the 1950s were the Middle East […]
Introduction to Energy Storage
Electricity is rarely stored but instead is usually converted to another energy form, such as electrochemical, potential or thermal. As a result, energy demand and supply need to be carefully balanced. This was more achievable with the traditional grid system using predictable fuel sources such as fossil fuels and nuclear fuel than it is with […]
Hydroelectric Power – Technical Background
A range of technical factors need to be considered when planning a hydroelectric power plant: the amount of power that can be generated, the type of hydropower that can be produced and the ability of the hydropower plant to meet changing electricity demands at short notice. All these factors can help developers decide whether a […]
Power Generating Capacity
NRG Expert has also identified another, perhaps more challenging, threat to energy security: there is a serious lack of power generation capacity under construction or in the planning stages. We estimate that by 2032 electricity demand will not meet electricity supply unless new, currently unplanned generation capacity is brought online. This issue may be further […]
Geothermal Energy Costs
Geothermal power generation typically involves relatively high levels of capital investment. Such expenditure, required to prove the geothermal resource capacity, involves some risk. Geothermal power projects involve high capital investment for exploration, drilling wells, and installation of the plant, but the projects have low operating costs because of the low marginal cost of fuel. Return […]
