Federal Excise Taxes placed on specific energy sources tend to reduce energy demand for these energy sources in both the short and the long run. The federal government imposes excise taxes on almost all petroleum products (including petroleum additives) and coal (see Table 1). The federal government also imposes federal excise taxes on many transportation uses of methanol, ethanol, natural gas, and propane and imposes a fee on electricity produced from nuclear power plants and nuclear power electricity.

Power generation and distribution networks are built with spare capacity to meet peak periods of energy consumption is usually a time when demand for heating and / or cooling is particularly acute accommodate. Normally, peak electricity demand in some cases last just a few hours every year. And while the networks have always had to cope with peaks in recent years, the electricity consumption during peak hours has increased dramatically in the afternoon. (more…)

Solar water heating for swimming pool rank as the most successful but least heralded commercial solar application. The use of solar energy for pool heating and the equipment and needs of pool owners make a perfect match. The storage unit for the solar heated water already exists—the swimming pool. The pump needed to push water through the solar collectors must be purchased irrespective of the technology used to heat the water. The pool owner merely has to purchase the solar collectors. Since those using the pool generally want the temperature of the pool to be no higher than 801F (271C), the solar collectors do not require a costly glass cover or expensive metal sheeting and piping.

Geographers researching the development of nuclear power have shifted emphasis from commercialization, cost, risk, public acceptance, and power plant siting in the 1950s through the early 1980s to reactor decommissioning and radioactive waste disposal since then. With nuclear power development on hold in most countries, attention has also been given to nuclear weapons facilities and weapons proliferation in an increasingly dangerous world. (more…)

Advanced technology global electrical grids may be more promising for renewables energy. With current transmission lines, even if costs per kilowatt-hour of PV arrays and turbines declined drastically and production rates were increased to millions per year like mass-produced automobiles, the grids of the United States and the world could not handle the load management demands. Power must flow where needed, when needed. Existing grids are hub-andspoke networks designed for central power plants tens to hundreds of kilometers from users. These need to be re-engineered into ‘‘smart grids’’––a global Internet and superhighway system for electricity. (more…)

Reductions in carbon intensity, C/E, the carbon emitted per unit of energy generated, reflect the degree to which societies decarbonize their energy sources. The long-term trend has been a shift from coal to oil to natural gas––hydrocarbons with decreasing C/H ratios emitting progressively less CO2 per joule. However, the increasing use of clean low-carbon fuels is not sustainable without somehow disposing of excess carbon because it opposes the trend in the abundance of fossil fuels, with coal resources being the most abundant followed by oil and gas.

Because a nuclear explosion in a nuclear power plant is impossible due to the low fuel enrichment, the worst conceivable accident is a severe loss-of-coolant accident (LOCA), leading to a core meltdown. Although the nuclear fission and fusion process would be immediately stopped by a control rod insertion, the radioactive fission products would continue to generate decay heat in the fuel. Thus, a LOCA producing core uncovering could cause the fuel to melt. In the most extreme case, a molten mass would fall to the bottom of the reactor, melting through the reactor pressure vessel and the underlying concrete, and eventually coming to rest about 6.1 m (20 ft) underground.

Nuclear engineers work in conjunction with health physicists to assure that all activities involving radiation exposure to nuclear power plant workers or to the public are kept well below the U.S. requirements stated in Title 10, Part 20 of the Code of Federal Regulations (10 CFR 20). In fact, the current industry practice is to apply the ALARA (‘‘as low as reasonably achievable’’) principle to every exposure-related activity. To this end, nuclear engineers have been widely successful in designing nuclear plants that limit the dose to the public. (more…)

Sir Arthur Eddington’s general address on subatomic energy at the 1930 World Power Conference in Berlin stirred the imagination of every scientist and engineer present. The challenge was clear: find a practical means of accessing, controlling, and using the enormous energy locked in the atom as predicted by Einstein’s remarkable mass–energy relation, E=mc2. On December 2, 1942, Enrico Fermi transformed Eddington’s visionary challenge into reality by producing the world’s first controlled, self-sustaining nuclear reactor, Chicago Pile 1. Six decades later, nuclear energy now produces 16% of the world’s electrical power. (more…)

In Europe, modern renewable energy sources technologies were explored thoroughly for the first time after the oil embargo/ price crisis of 1973. Notably, market introduction of renewable energy technology started in about 1985, but the renewable energy sources industry has become vital only during the past decade. Accordingly, relevant statistical renewable energy sources data have been systematically compiled only over the past decade, although reliable and consistent statistical renewable energy sources data, collected since 1989, exist for all 15 countries of the European Union and for Western Europe (defined here as the EU-15 plus Switzerland, Norway, and Iceland).
