Human population planningHuman population planning is the practice of managing the growth rate of a human population. The practice, traditionally referred to as population control, had historically been implemented mainly with the goal of increasing population growth, though from the 1950s to the 1980s, concerns about overpopulation and its effects on poverty, the environment and political stability led to efforts to reduce population growth rates in many countries.
Economics of nuclear power plantsNuclear power construction costs have varied significantly across the world and in time. Large and rapid increases in cost occurred during the 1970s, especially in the United States. Recent cost trends in countries such as Japan and Korea have been very different, including periods of stability and decline in costs. New nuclear power plants typically have high capital expenditure for building plants. Fuel, operational, and maintenance costs are relatively small components of the total cost.
Centrale solaire d'AndasolEn 2008 la centrale solaire Andasol 1 était la plus puissante centrale solaire thermodynamique d'Europe avec . Elle est située près de Guadix en Andalousie (Espagne). La centrale a démarré en novembre 2008 et génère une puissance-crête de avec les extensions et sa production est de 175 à d'énergie électrique par an. Construite sur un site privilégié à d'altitude, elle bénéficie d'un climat semi-aride qui se traduit par une insolation directe de /an (soit, en moyenne, une puissance de ).
Nuclear energy policyNuclear energy policy is a national and international policy concerning some or all aspects of nuclear energy and the nuclear fuel cycle, such as uranium mining, ore concentration, conversion, enrichment for nuclear fuel, generating electricity by nuclear power, storing and reprocessing spent nuclear fuel, and disposal of radioactive waste. Nuclear energy policies often include the regulation of energy use and standards relating to the nuclear fuel cycle.
