Three hydroelectric plants were opened between 1965 and 1970, at Jalālābād, Naghlu, and Mahipar, near Kabul; another, at Kajaki, in the upper Helmand River Valley, was opened in the mid-1970s. In addition to the Naghlu, Mahi Par, and Kajaki plants, other hydroelectric facilities that were operational as of 2002 included plants at Sarobi, west of [...]

While a-Si suffers from lower electronic performance compared to c-Si, it is much more flexible in its applications. It may also produce savings on silicon material cost, as a-Si layers can be made thinner than c-Si. One advantage is that a-Si can be deposited at very low temperatures, as low as 75 degrees Celsius. This [...]
While oil has many other important uses (lubrication, plastics, roadways, roofing) this section considers only its use as an energy source. The CMO is a powerful means of understanding the difficulty of replacing oil energy by other sources. SRI International chemist Ripudaman Malhotra, working with Crane and colleague Ed Kinderman, used it to describe the [...]
Large energy subsidies are present in many countries (Barker ”et al.”, 2001:567-568). Currently governments subsidize fossil fuels by $557 billion per year. Economic theory indicates that the optimal policy would be to remove coal mining and burning subsidies and replace them with optimal taxes. Global studies indicate that even without introducing taxes, subsidy and trade [...]
The technical name of the design is ”Fixed Mirror Distributed Focus Solar Power System”. The main reason for its development was to eliminate the cost of having the mirror move with the sun as a tracking parabolic mirror does. A fixed parabolic mirror creates a changing image of the sun as it moves along the [...]
The spacecraft has the shape of an octagonal prism, approximately 1.7 m on a side, with four fixed gallium arsenide solar panels in a windmill arrangement, a fixed 1.5 m X-band high-gain radio antenna with a magnetometer mounted on the antenna feed, and an X-ray solar monitor on one end (the forward deck), with the [...]
Some have argued that feed-in tariffs can be used to accelerate the pace at which renewable energy technologies become cost-competitive with electricity provided from the grid, to obtain grid parity. The rapid deployment of renewable energy under feed-in tariffs seen in countries like Germany, Denmark and Spain has undoubtedly contributed to reducing technology costs, and [...]
Those not satisfied with the third-party grid approach to green energy via the power grid can install their own locally based renewable energy system. Renewable energy electrical systems from solar to wind to even local hydro-power in some cases, are some of the many types of renewable energy systems available locally. Additionally, for those interested [...]
According to advocates, the idea of a national system would do for the US energy economy what Dwight Eisenhower’s Interstate Highway System did for efficient distribution of products. Solar power from Arizona would be able to supply manufacturing in Ohio, or evening wind power from the Northeast could be used to supply power peak demand [...]
At high noon on a cloudless day at the equator, the power of the sun is about 1 kW/m², on the Earth’s surface, to a plane that is perpendicular to the sun’s rays. As such, PV arrays can track the sun through each day to greatly enhance energy collection. However, tracking devices add cost, and [...]
EPRI champions the use of all generation technologies which are efficient, reliable, safe, and environmentally benign, but has concluded that coal and nuclear power will still supply two-thirds of our energy by 2050. The organization sees renewables such as wind and biomass supplying only a quarter of the electricity in 2050, and predicts solar power [...]
The BA-35 was targeted at students studying finance and was available from 1985 to the late 2000s; though it contained a full set of TVM functions, it lacked the advanced scientific calculator functions of later models of the BA-II. It was the most affordable calculator for time-value-of-money calculations. Features: Preprogrammed financial and accounting functions, including [...]
