China-US climate deal may drive developing world action
China’s pledge to cap carbon emissions may set an example for the developing world to follow, say climate change experts. The joint pledge by the world’s two biggest polluters, China and the United States, to limit greenhouse gas emissions could encourage developing nations to address climate change, says Saleemul Huq, director of the International Centre for Climate Change and ...

Competitive without subsidies: Navigating the booming solar market in Chile
By Susan Kraemer on Nov 11, 2014 Solar developers are flocking to the recently opened new market for renewable energy in Chile, a nation dependent on imported diesel, coal and gas, no fossil fuel subsidies and the world’s best insolation. But what are the on-the-ground challenges? Chile is a long narrow coastal country served almost entirely by a single long grid with a transmission gap ...

Eco-Brella: prototype development of the umbrella as harvester of solar and wind energies
The familiar umbrella has been redesigned for power harvesting from renewable energy sources resulting in the Eco-Brella . Several engineering technologies are utilised: aerodynamics for fin design, mechatronics for power management, materials for thermoelectric and solar film, CAD for the layout, and heat transfer for human comfort. The result is a sustainable design capable of harvesting ...

Desertec: slow death or healthy evolution?
After five years the Desertec Industrial Initiative will cease to exist in its current form. The question for the industry is whether this is a natural progression or a cause for concern. It has been a bumpy few weeks even by the turbulent standards of the Desertec Industrial Initiative’s short history. After a dwindling number of backers earlier this year decided to maintain the Dii as a ...

Optimal sizing of a hybrid energy system for a semi-arid climate using an evolutionary algorithm
The use of a genetic algorithm (GA) for optimal sizing of an off-grid hybrid renewable energy system (HRES) is reported. As a pre-feasibility analysis and to determine the appropriate HRES type to be studied, wind energy potential and solar irradiation are first examined for the considered region (Tehran, Iran). These are inputs of the algorithm, and are assessed throughout a year utilising ...

Optimum use of renewable energy resources to generate electricity via hybrid system
The necessity of hybrid energy system is gaining more importance day by day as it incorporates two or more than two renewable energy resources that when integrated overcome limitations inherent in either. Hybrid energy system has been seen as an excellent solution for electrification of rural place where the grid extension is difficult and economically not feasible. Such system may consist of ...

Political will is only barrier to 100% renewables
A new handbook shows how forward-looking communities around the world are already moving away from reliance on fossil fuels and generating their own power with 100% renewables − while also becoming more prosperous and creating jobs. The report, How to Achieve 100% Renewable Energy, is being released today, ahead of the UN Climate Summit in New York next Tuesday (September 23), when the UN ...

Fossil Fuel Development in the Arctic is a Bad Investment
Even master chess players can miss a great move when they have been primed to look for a different one. To explore this phenomenon, researchers tracked master chess players’ eye movements when given chessboards with different layouts. With the first board, players could reach checkmate using a familiar move. When given the second chessboard, the players' eyes kept looking at the pieces ...

China may be ready to kick coal habit
There are still doubts. The statistics might be proved wrong. But it looks as if China might be starting to wean itself off its coal consumption habit. China produces and consumes nearly as much coal as the rest of the world combined. Coal, the most polluting of all energy sources, has powered the growth of China’s flyaway economy. But as incomes have risen, so has pollution. The country ...

How to plan hydropower stations for the future
The hydropower plants of tomorrow won’t only produce energy. Constructing dams will also provide new drinking water sources, irrigation for crops, and new waterways for transport. In the words of most of the scientists here at World Water Week in Stockholm, Sweden, they will be ‘multipurpose’. This means that each plant design will be a one-off. And, more importantly, each will ...

India’s Potential in Harnessing the Alternate Energy Sources
Long queues for gasoline, high prices and shortage of gasoline are the signs which show that how natural resources are on the verge of depletion. This shows that it is high time for us to view how to utilize natural resources. India is mainly depended on import of petroleum products for its energy requirements. It meets its requirements by importing 70% of petroleum products. This is a point of ...

Geothermal Power Approaches 12,000 Megawatts Worldwide
In 2013, world geothermal electricity-generating capacity grew 3 percent to top 11,700 megawatts across 24 countries. Although some other renewable energy technologies are seeing much faster growth—wind power has expanded 21 percent per year since 2008, for example, while solar power has grown at a blistering 53 percent annual rate—this was geothermal’s best year since the ...

Boom-or-doom riddle for nuclear industry
The headline figures for 2014 from the nuclear industry describe a worldwide boom in progress, with 73 reactors presently being built and another 481 new ones either planned or approved. The World Nuclear Association (WNA) official website paints a rosy picture of an industry expected to expand dramatically by 2030. It says that over the period 1996 to 2013 the world retired 66 reactors, and 71 ...

Highly-Standardize Batteries for Express Convenience
Batteries of any kind matters to the preservation of renewable energies. Hence, we are referring to the ways of preservation of renewable energies here, including solar and wind energy. In fact, the availability of solar and wind energy is passively argued in several times because solar energy is precisely presence in daylight. Yet, solar power systems can work overnight in a way that experts ...

Solar Streetlights: Bright Side
The world’s largest demand of energy resources is the renewable one. These includes the bio fuel, geothermal energy, wind power, hydro-electricity and solar power. Among the names being mentioned, experts preferably chosen solar power as one of the great source that must be cultivate to solve the economic issues and problems in the earth. Otherwise, scientists develop new discoveries and ...

Climatic Catastrophes And The Role Of Solar Power
The world is witnessing a drastic negative change in the climate of all regions owing to the rapid increase in the burning of fossil fuels as well as utilization of other non-renewable sources for energy production. These worst fears of increasing natural disasters, extreme weather and melting of Earth’s icecaps were confirmed by the recent release of IPCC’s climate assessment report. ...

Negative Power Generation Aspects of Adopting Renewable Sources
Renewable energy resources are all the rage nowadays on a global scale with the biggest benefit of providing unlimited access without any fear of depletion or running out in the near future. It also provides the edge of saving the continuously decreasing fossil fuel reserves and to protect the planet against the harmful pollution caused by the burning of all non-renewable resources. Some common ...

Get Rid of Global Energy Poverty
This modern 21st century still contains millions of people who do not have sufficient access to electricity or clean cooking facilities. Energy poverty can basically be described as the lack of access to even the most basic needs involving lights and cooking. The income disparity worldwide has increased the gap between one portion of the population enjoying luxuries and gadget while the other ...

Saving Renewable Energy for a Rainy Day
Despite advances in renewable energy technologies, one of the largest hurdles in their widespread adoption has been their intermittent reliability. Energy is only useful if it is available as the grid demands it, which is why concerns about carbon emissions are overridden in favor of the more dependable oil, coal and gas for baseload power. In order for renewable sources such as wind and solar ...
