Renewable energy debate – Introduction

renewable energy debate about the constraints and opportunities associated with the use of renewable energy. Renewable electricity production, from sources such as wind power and solar power, is sometimes criticized for being variable or intermittent. However, the International Energy Agency has stated that deployment of renewable technologies usually increases the diversity of electricity sources and, [...]

Colin Campbell (geologist) – Current debate

Global oil discovery peaked in 1964 , and since the early 1980s oil production has outpaced new discoveries. The world currently consumes oil at the rate of 84 million barrel per day (31 billion barrels/year, or 151 m³/s), and consumption is rising, particularly in China. According to Campbell: * There are no new potential oil [...]

Wind power generation in New Zealand (2007) – Wind power generation

Electricity generation via wind turbines is uncontrolled, in that the wind blows or not irrespective of the timing of the demand for electricity. Measurements of the generation over half-hourly intervals are supplied to the Electricity Commission. There are isolated wind turbines at Brooklyn and Gebbie’s Pass. At the Te Rere Hau wind farm there are [...]

Whitelee Wind Farm – Introduction

Whitelee wind farm is the largest onshore wind farm in Europe, with 140 Siemens wind turbines and a total capacity of 322 megawatts (MW). Whitelee was developed and is operated by ScottishPower Renewables, which is part of the Spanish company Iberdrola. Positioned 370 metres (1200 feet) above sea level and 15 kilometres (9 miles) outside [...]

Renewable resource – Renewable energy

Solar energy is the energy derived directly from the Sun. Along with nuclear energy, it is the most abundant source of energy on Earth. The fastest growing type of alternative energy, increasing at 50 percent a year, is the photovoltaic cell, which converts sunlight directly into electricity. The Sun yearly delivers more than 10,000 times [...]

History of wind power – Late Middle Ages

The first windmills in Europe appear in sources dating to the twelfth century. These early European windmills were horizontal-axle sunk post mills. The earliest certain reference to such a horizontal-axle windmill dates from 1185, in Weedley, Yorkshire, although a number of earlier but less certainly dated twelfth century European sources referring to windmills have also [...]

Economics of climate change mitigation – Energy sector subsidies

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 [...]

Wind power in Maine – Redington and Black Nubble

In 2005, Maine Mountain Power (MMP) filed an application with the Maine Land Use Regulation Committee (LURC) for a permit to develop a 30-turbine wind farm on Mount Redington and neighboring Black Nubble . After years of contentious debate, the proposal was voted down by the LURC in 2007. The summit of Redington was seen [...]

Wind power in the United Kingdom – Capacity factor and related issues

Because the level at which a wind farm operates is determined by the wind speed at any particular time, capacity factor bears limited relation to the hours it operates. In comparison, thermal power stations must run at or near their full capacities at all times in order to achieve maximum efficiency. This makes them ill-suited [...]

Wind power in the Republic of Ireland – Arklow Bank Wind Park

The Arklow Bank Wind Park, located 10 kilometers (6.2 miles) off the coast of Arklow on the Arklow Bank in the Irish Sea, was Ireland’s first off-shore wind farm. The wind farm is owned and built by GE Energy and was co-developed by Airtricity and GE Energy. The site currently has 7 GE Energy 3.6 [...]

Shiloh Wind Power Plant – Shiloh II

EnXco started commercial operation of the 150-megawatt Shiloh II wind farm in February 2009. The wind farm has 75& turbines, each generating up to 2& megawatts. It produces enough energy for 74,000 homes. EnXco has a 20-year contract to sell the power to Pacific Gas and Electric Co. Adapted from the Wikipedia article Shiloh Wind [...]
