Reply by the Central Pollution Control Board (CPCB) in compliance to the National Green Tribunal (NGT) order dated January 21, 2024 in the matter of ‘News item titled “Feeling anxious? Toxic air could be to blame” appearing in Times of India dated 10.10.2023’. NGT had directed CPCB to file a …
Make clean fuel or feed the world? That's the dilemma facing biofuel producers now that the world food crisis is making the turning of food crops into biofuel seem increasingly irresponsible. But maybe there's a way out. Mariam Sticklen of Michigan State University in East Lansing and colleagues have engineered …
While green campaigners push for ever more wind turbines, a new wave of environmentally motivated engineers is already considering turbines to be a little old-school. One of the pioneers of the concept of a kite as a renewable energy source is Peter Lynn, a New Zealand kite designer.
Plants should source equipment, services from the US. Export-Import Bank of the United States (EX-IM Bank) is open to funding Indian nuclear power projects that will source equipment and services from the US. If a US company is involved in providing equipment and services for nuclear power project in India, …
Close on the heels of quality issues related to some of the wind turbine blades supplied in the US and other parts of the world, Suzlon Energy - the fifth largest wind power equipment manufacturer in the world - is facing more problems in the US. Suzlon Rotor Corporation, its …
Chandigarh In the agrarian states of Punjab and Haryana, power cuts have been the order of the day for years. This, in turn, has affected economic development in these states. While the two states have decided to spend almost one-third of their five-year Plan for 2007-12 on power projects, they …
A City-based engineer Prabhakar Wawge, has come up with a solar water heating system, which can be used in multistoried building without using terrace area. It can be used as a wall integrated solar water heating system and does not require any pumping mechanism for circulation. Wawge got the patent …
George Unzelman, has more than 50 years of refining experience and has been in the industry during some of its most dramatic changes-some predicted, some results of opposition. In an opinion editorial, Unzelman shares his observations and predictions moving forward.
A hybrid plant combines wind, solar and hybrid power conditioning unit with a battery to supply electricity to remote areas. Locations that relied on conventional fuel can now take advantage of natural energy. A stand-alone wind system with a SPV (solar photovoltaic system) is the best hybrid combination of all …
Fuel cells are an important enabling technology for the hydrogen economy and have the potential to revolutionize the way we power our nation, offering cleaner, more-efficient alternatives to the combustion of gasoline and other fossil fuels. Fuel cells have the potential to replace the internal combustion engine in vehicles and …

The radiations from the sun can be converted into electrical energy using devices like solar cells. The device that can directly convert solar energy into usable electrical energy is known as solar cell or photovoltaic cell. The voltage generated from a single photovoltaic cell is typically only a fraction of …
A recent development in solar energy is a solar tower/chimney.It is a method used for large-scale generation of electricity from solar radiation.The principle is very simple.It is based on the well known principle of greenhouse effect,chimney updraft effect, and wind turbine. Ambient air is drawn into a very large circular …
Climate change is one of the key challenges of this century. Specifically, balancing climate change mitigation and increased energy needs in developing countries poses a serious dilemma that can only be reconciled with new and improved clean energy technologies. However, to accelerate innovation in the energy sector, certain factors must …
inorganic solar cells used today are also quite bulky. Initial costs also seem to be a major deterrent in the spread of solar energy. A us-Austrian team led by 2001 Nobel laureate Alan Heeger has gone some way in mending matters. In 2005, the team had come up with a …
Bioethanol and biodiesel are coming under increased criticism for diverting food resources and driving up food prices across the world. Second-generation biofuels are gaining credibility as a solution. Praj Industries has achieved a major breakthrough technology for the production of bioethanol from lignocellulosic feedstock, creating an alternate agri-waste feedstock for …
THE only hurdle to the large-scale use of solar energy is the state of the technology. In terms of dollar-per-watt of electricity, traditional fossil fuels are still much more efficient. But that is rapidly changing, and what was at $3-$4 per watt even a few years ago is at the …
They call it flammable ice, and it could be the world's last great source of carbon-based fuel - assuming we can mine methane hydrates, crystal lattices of ice that trap methane beneath ocean beds and permafrost. One problem with extracting this methane is that you have to melt the ice …
A few U.S. energy companies have drawn up plans for synfuels plants that would produce millions of barrels of the alternative fuel annually. The technology is gaining support from a a group of climate scientists who believe that, barrel for barrel, synfuels can emit less carbon dioxide (CO2) than oil …
Technology Smooths the Way for Home Wind-Power Turbines New Ways to Store Solar Energy for Nighttime and Cloudy Days (April 15, 2008) No one tracks the number of small-scale residential wind turbines
