The power coefficient of windmills in ideal conditions
The windmill efficiency, also designated as the power coefficient, is defined as the ratio of the actual power output to the power present in the free stream of a fluid flowing through the same cross-sectional area. There are remarks in the literature to the effect that the power coefficient of actual windmills is very close to the ideal power coefficient or Betz limit of 0.5926. In this paper, ...

DOE announces third round of START program
On February 25, 2015, the U.S. Department of Energy (DOE) announced the third round of Strategic Technical Assistance Response Team (START) Renewable Energy Project Development Assistance that provides tribal governments and entities with support to produce clean and renewable energy. The START program was launched in December 2011 and has helped 21 tribal communities advance solar, wind, ...

Energetic and exergetic assessment of solar and wind potentials in Europe
This paper deals with a physics–based assessment of renewable energy potential in Europe, particularly solar and wind energy sources, using two literature models. A sensibility analysis with the weather data is first done. Actual temperature, pressure, relative humidity, global radiation and wind speed data are employed to develop energy and exergy maps for Europe, based on iso–areas of land–use. ...

Energy and exergy assessments for potential wind power in Turkey
The main objective of the study is to estimate wind power potential of Turkey and provide suitable data for evaluating potential wind power by using the wind data collected at 23 different wind-monitoring stations. In this study, energy and exergy analyses of wind power are used to estimate wind power potential in these areas. Exergy analysis of wind power is investigated according to air ...

Study on environmental impact model of grid-connected wind power generation
As a clean and renewable energy source, wind power is independent from the traditional external energy change, which makes it one of the most promising ways of clean energy generation. It is well known that wind power has obvious energy saving efficiency. But for long-term consideration, wind power generation still has certain impacts on human life. Therefore, standing in the point of the ...

Which is more efficient solar or wind energy?
Before we start our reasoning, we'd like to remind you that both are renewables, and therefore both are great energy options to turn to to improve our planet and to break our addiction to oil and gas. Today we will try to answer a question that we often ask ourselves when we are interested in renewable energies : between solar and wind energy, which is the most efficient? First, let's take a ...

Mobilizing Climate Investment: The role of international climate finance in creating scaled-up, low-carbon energy
Between now and 2050, developing countries need an estimated $531 billion per year of additional investment in energy supply and demand technologies in order to limit global temperature rise to 2° C above pre-industrial levels. To achieve this scale of investment, developing country governments and custodians of international public finance will need to deploy limited public finance in ways ...

From Climate Crisis to a Clean Economy: A Vision for a New World by 2030
Looking for a little inspiration? Me, too. We’ve all heard the statistics. One million species worldwide are currently at risk of extinction. Over 5 trillion pieces of plastic are polluting our oceans. The day the Arctic fully melts may happen within our lifetimes. And perhaps most shockingly, the latest report from the Intergovernmental Panel on Climate Change tells us that we have a ...

Powering Efficiency: Effective Energy Management in Facilities
Effective energy management is a crucial aspect of facility management that holds the key to unlocking significant cost savings, enhancing sustainability, and minimising environmental impact. By implementing strategic energy management practices, facilities can optimise their energy consumption, improve operational efficiency, and contribute to a greener future. In this week’s article, we ...

Could food shortages bring down civilization?
“In early 2008, Saudi Arabia announced that, after being self-sufficient in wheat for over 20 years, the non-replenishable aquifer it had been pumping for irrigation was largely depleted,” writes Lester R. Brown in his new book, Plan B 4.0: Mobilizing to Save Civilization (W.W. Norton & Company). “In response, officials said they would reduce their wheat harvest by one eighth each year ...
