Why Do More Than 50,000 Families in Bangladesh Buy a Solar Home System Every Month?

Why Do More Than 50,000 Families in Bangladesh Buy a Solar Home System Every Month? | Sustainable Energy | Scoop.it
“Does the solar home system work? Do you really get better lights? Or, is it just a big fuss?’ I have been asking solar home systems households in rural Bangladesh these basic questions for the past five years as part of my implementation review missions for the Rural Electrification and Renewable Energy Development program, which has installed over  2.8 million solar home systems since 2002. This has so far contributed to a 9% increase in access to electricity in Bangladesh.

Energy Efficiency Will Help India Save Money and Breathe Easier

Energy Efficiency Will Help India Save Money and Breathe Easier | Sustainable Energy | Scoop.it

Energy efficient lighting, windows, and air conditioning get more productivity out of less energy and save money at the same time. This also reduces the surging energy demand that leads to frequent blackouts.

NRDC’s India Initiative works with Indian partners to spread the benefits of efficiency across the nation. Our team just released a case study showing how Godrej & Boyce—one of India’s largest industrial corporations—transformed its South Mumbai headquarters into an energy-efficient flagship.

Japan's Quiet Skyscraper-Demolition Technique Generates Energy

Japan's Quiet Skyscraper-Demolition Technique Generates Energy | Sustainable Energy | Scoop.it

Taisei Corporation is using its Ecological Reproduction System (Tecorep) to gradually lower the Grand Prince Hotel Akasaka, and bemused passersby have already witnessed the 140m-high (about 460 feet) tower quietly shrink to 110m (about 360 feet). It’s a far more elegant method when compared with the much-unchanged tack of getting something big and heavy and smashing it into a building, or the presumably fun but incredibly messy process of blowing it up. Buildings are of course dismantled using cranes already, but only from the exterior and for towers under 100m — and they’re far from green. Having investigated new methods since 2008, Taisei is suggesting that for buildings over 100m we need to adopt a new approach.

India: Forget the grid, community power is here - A New Era of Entrepreneurs

It just so happens that taking advantage of this proposition solves another vexing problem for mobile phone providers — costly diesel. By switching out the expensive diesel gen sets that power their off-grid “base stations” — radio towers that convert electricity into radio waves — the companies save money. In India alone there are an estimated 400,000 towers over 150,000 of which don’t have reliable access to the grid.

 

This is where Community Power comes in. These base stations act as anchor clients for small scale energy projects by committing to the purchase of a majority of the power supply generated by a company like OMC. With this guaranteed revenue stream in hand, OMC can then sell their excess power generation to local communities via mini-grids, transportable batteries, or by directly charging applications (like phones) on site. This helps the mobile phone companies keep their customers phones charged, it reduces their monthly power bills, and it electrify’s rural communities — this is community power.

Can Renewables Save India's Failing Grid? : Climate Desk

Can Renewables Save India's Failing Grid? : Climate Desk | Sustainable Energy | Scoop.it
On Tuesday, Rishabh Agarwal, a 25-year-old freelance photographer, rushed to meet clients in New Delhi, at the heart of one of the busiest and most crowded metropolitan areas on Earth. His timing couldn’t have been worse: the biggest blackout in history, two consecutive days of grid collapse that left almost half of India’s population without power.

Agarwal‘s first problem: no transport. “Delhi Metro, which is heart and soul of the city, also failed,” Agarwal said by email. So he took his car. Mistake. Traffic lights were out; buses were unable to absorb the sudden surge of commuters. The weather was nice, so Agarwal and other locals assumed this was a normal New Delhi blackout, the sort that happens across the summer. Then he checked the news.

Can Efficiency Counter a Loss of Nuclear Power?

Can Efficiency Counter a Loss of Nuclear Power? | Sustainable Energy | Scoop.it

That argument is particularly common in New York State and in Vermont, where state governments are trying to close nuclear reactors within their borders. So, how effectively can efficiency replace a reactor, making up for the loss of this zero-carbon energy source?

Japanese Solar Energy Industry Soaring

Japanese Solar Energy Industry Soaring | Sustainable Energy | Scoop.it

In the wake of the tragic Fukushima Daiichi nuclear disaster in March of 2011 there was renewed public and political support for weaning the country off nuclear power altogether. Currently 27% of Japan’s electricity demand is met by nuclear power, but according to a new report by researchers at the University of Texas, Tokyo could use solar photovoltaic (PV) generation as a “baseload” power.

According to the report, “Potential for rooftop photovoltaics in Tokyo to replace nuclear capacity”, 300 square kilometres of suitable rooftop space in Tokyo could support 43.1 GW of PV to offset the demand currently filled by nuclear, alongside an existing 7.28 GW of pumped hydro storage available.

Why geoengineering has immediate appeal to China

Why geoengineering has immediate appeal to China | Sustainable Energy | Scoop.it

The political dilemma over geoengineeringdeliberate, large-scale intervention in the climate system designed to counter global warming or offset some of its effects – will perhaps be most acute in China.


In December, the country listed geoengineering among its Earth science research priorities, in a marked shift in the international climate change landscape noticed by China specialists Kingsley Edney and Jonathan Symons.

A Smart Energy Strategy in Japan: What's the Vision?

A Smart Energy Strategy in Japan: What's the Vision? | Sustainable Energy | Scoop.it

Japan’s national energy strategy experienced a 9.0 quake of its own in 2011 as a result of the twin incidents of the March 11 tsunami and subsequent Fukushima nuclear accident. It rattled many assumptions about energy sources and electrical grid configurations for its major corporations too. A recent Silicon Valley Technology Forum hosted by Fujitsu served as an excellent opportunity to hear how these large-scale events have shaped thinking and R&D in the leading information and communications (ICT) company in Japan, which also happens to be the third largest ICT company in the world. Their thoughts and R&D can help contribute to North American ideas and directions to improve our energy surety as well as grid reliability and resiliency that the Smart Grid’s modernization activities must deliver.

Fujitsu’s Smart Energy vision focuses on three trends:

  1. local generation and consumption
  2. increased sensing and remote control in transmission and distribution grids
  3. increased demand response (DR) technologies and distribution grid-sited storage.

Solar panels help retain irrigation water

Solar panels help retain irrigation water | Sustainable Energy | Scoop.it

This solar panel laid on the vast stretches of agricultural channels in Gujarat, India generates 1 MW of electricity per kilometer & prevents evaporation of 1 crore(10,000,000) liters of water every year, a very great help to local (and not so local) agriculture.

China dramatically increased its renewable energy production capacity in 2011, tripling output in solar power alone, but environmentalists warn an unwavering reliance on coal to fulfill 70 percent of its energy needs is offsetting the benefits of this new clean development, according to The Guardian.
