Water Hungry Coal - Burning South Africa’s water to produce electricity
Safe, affordable and accessible water is regarded as one of our planet’s scarcest natural resources. This is particularly true on the African continent, where water insecurity is often an everyday reality. At the same time, equitable access to water is fundamental to life and human health and well-being. South Africa already struggles with water scarcity, and it is predicted that the ...

Utilization of fly ash in construction industries for environment management
Abstract Fly ash is naturally cementations coal combustion by-product. A fine glass powder recovered from the gases of burning coal during the production of electricity is fly ash. The combustion of powdered coal in thermal power plants produces fly ash. Disposal of high amount of fly ash from thermal power plants absorb huge amount of water, energy and land area by ash ponds. Generation of ...

Energy efficiency indicators for public electricity production from fossil fuels
Electricity production is responsible for 32% of total global fossil fuel use, accounting for 132 EJ, and 41%, or 10.9 Gt of energy-related CO2 emissions. Improving the efficiency of electricity production therefore offers economic benefits and a significant opportunity for reducing dependence on fossil fuels, which helps to combat climate change and improve energy security. A set of indicators ...

What is the future of King Coal in China?
When it comes to coal consumption, no other nation comes close to China. The country reigns as the world’s largest coal user, burning almost half of the global total each year. About 70 percent of China’s total energy consumption and nearly 80 percent of its electricity production come from coal, and its recent shift from being a historical net coal exporter to the world’s ...

Why Raw material Substitution can harm producers
The evolution of technologies, high prices, new regulations or high risks on supplies threatens the position of certain raw materials to substitutions. The substitution of one material for another industry takes many forms and can have a significant impact, on both the market and involved companies, said the research firm EY in a recent study on "super cycle" for mining and oil companies. "The ...

Exergy analysis of geothermal electricity using the Kalina cycle
The geothermal energy that is stored in the earth is so vast that could supply all the energy needed by humanity. The difficulty in tapping this energy lies in its diffusivity. The geothermal energy in regions near volcanoes is close to the surface and easy to use economically. In this paper a vapour dominated system will be examined. The electricity that is produced from such a system is ...

Analysis of wind power in Danish electricity supply, 2005-2007
It is frequently said that wind power covers about 20% of electricity consumption in Denmark. The correct statement is that production of electricity by Danish wind turbines corresponds to about 20% of electricity consumption. A considerable fraction of the energy produced by wind turbines is exported to neighbouring countries and therefore is not used in Denmark. But how does one know that the ...

President Obama’s Climate Action Plan: Can it Shift the World Away from Coal?
While reactions to President Obama’s newly announced climate plan have focused on domestic action, the plan actually has potentially significant repercussions for the rest of the world. These repercussions will come in part through his commitment to limit U.S. investments in new coal-fired power plants overseas. If fully implemented, the plan will help ensure that the U.S. government ...

Fact Sheet: U.S. electricity markets increasingly favor alternatives to coal
The U.S. electric power system is gradually shifting toward cleaner forms of generation. One sign of this transition is the declining use of coal for electric power production. In 2011, use of coal for U.S. power generation dropped to its lowest level in more than a decade, according to the federal government’s independent U.S. Energy Information Administration (EIA). In fact, the EIA ...
