Two supermarkets are making lemonade out of lemons the green way—by converting their spoiled food into energy. Grocery chains Ralphs and Food 4 Less (both part of the Kroger Co.) have joined forces with FEED Resource Recovery to make use of the rotten and expired foods that their markets don’t sell. Any food that can’t be sold or donated will be transformed into energy to help run their distribution center in Compton.

When architect Ed Mazria announced that buildings account for nearly 50% of man-made greenhouse gas emissions, the building industry was taken aback. After a long career in passive solar architecture, he has taken on the goal of steeply reducing the carbon footprint of architecture – most notably with his 2030 Challenge, which aims to eliminate the use of fossil fuels in new construction, and to cut the use of fossil fuels in existing buildings by 50% by 2030. To help hit those targets, Mazria is launching a new initiative called the 2030 Palette—a robust, visually oriented online design tool which strives to help produce low-impact, people friendly projects. We recently visited Mazria’s offices in Santa Fe, where we spoke to the architect in-depth about his work and how sustainable development can save us from the worst climate change has to offer.

Every once in a while an idea comes along that is so unlike anything before that it defies reference. Take Belatchew Lab Architecture’s Strawscraper, a skyscraper covered in hair that can harness the energy of the wind. The building looks as though it belongs at the bottom of the sea, with its long anemone-like hair, but its technology is planted firmly on the terra firma of the future.

Today is National Bike to Work Day, and all across America, people are ditching their cars and trucks for a cleaner, healthier journey via bicycle. Our friends at Voltaic Systems joined in the fun to support NYC’s Bike to Work Day, and it’s no surprise that they added their own solar-powered flair to the day’s festivities. Company staffers decked out a commuter bicycle and with a custom-built bike trailer carrying 60+ Watts of portable solar panels, 180 Watt hours of charging capacity, and lots of connectors to charge up smartphones, tablets and even a MacBook, in an effort to show New Yorkers how much fun can be had when human and solar power are combined.

In the developing world, mortality rates for expectant mothers total over 300,000 deaths each year. The WE CARE Solar Suitcase is a brilliant new device that aims to reduce this figure by providing hospitals in off-grid areas with access to a steady source of energy and light. Designed by Dr. Laura Stachel and her husband Hal Aronson, the system includes high-efficiency LED lights, a universal cellphone charger, 12V DC outlets, a set of 40 or 80 watt solar panels, and a 12 amp-hour sealed lead-acid battery.

Japan has hemmed and hawed about closing its nuclear reactors after the 2011 Fukushima disaster. At first there was talk of closing down all reactors, but the motion was whittled down to affect just those that fail rigorous safety testing, and finally none at all. A panel of seismic experts just announced that one of Japan’s oldest reactors sits on a highly earthquake-prone site and should be shuttered permanently – and the government is taking the first steps towards shutting it down.

A team from the U.S. Naval Research Laboratory (NRL) have broken their own record after flying their hydrogen fuel cell powered-Ion Tiger UAV for an astonishing 48 hours and 1 minute last month. The UAV, which used liquid hydrogen fuel in its  new, NRL-developed, cryogenic fuel storage tank and delivery system, broke its previous record of 26 hours and 2 minutes which it set in 2009.

Alternative energy company Urban Green Energy (UGE) has announced the launch of its new vertical axis wind turbine, the VisionAIR. The turbine was the result of over a year of dedicated testing at UGE’s research and development facility and according to the company, and it could be used in distributed energy applications, which are typically located near the point of energy consumption. The VisionAIR will debut at the Beijing International Garden Expo next week.

Offshore wind farms and tidal energy facilities harness the power of the wind and the ocean – but why should we have separate turbines for each task? Offshore technology company Mitsui is developing a hybrid wind-current power generating system that combines a floating vertical-axis wind turbine with an underwater turbine that generates power from ocean currents. The clever apparatus would cut down on material waste, and it could produce twice as much energy as a conventional wind turbine.

Hyundai isn’t joking when it claims it wants to fight global warming. The car manufacturer just announced that it plans to install what will be South Korea’s largest solar photovoltaic system on the rooftops of its plant in Asan. Working with thermal power company Korea Midland Power Ltd. (KOMIPO), Hyundai plans to install 40,000 solar photovoltaic modules on the rooftops of the plant’s press, welding, assembly and engine buildings by the end of the year. The giant rooftop solar plant will curb 5,600 tons of CO2 emissions – the equivalent of planting 1.12 million pine trees.

The Window Socket is an idea so fabulously simple, it’s slightly amazing that we haven’t seen one before. Designed by Kyuho Song & Boa Oh, the charger sticks to a window and draws solar power to an internal battery, which enables one to either plug in small devices to the outlet right there and then, or save the stored power for use during night time hours.

Yale researchers recently discovered a way to boost the efficiency of solar cells by a whopping 38 percent by coating them with a fluorescent dye. Polymer solar cells are popular for their low cost, low weight, large area and mechanical flexibility, according to Physorg, but they only convert roughly 50 percent of the solar energy absorbed into usable electricity. The organic squaraine dye improves light absorption and recycles electrons, thereby hastening the light to energy conversion process.

When it comes to capturing solar energy, plants are first in their class. Able to function at nearly 100 percent quantum efficiency, they can produce an equal number of electrons for each photon captured. Using these photons to split water into hydrogen and oxygen, the resulting electrons are able to create sugars that help the plant to live and reproduce. Researchers at the University of Georgia have developed a way to harness the power of the photosynthetic process to generate a clean form of electricity. Ramaraja Ramasamy, assistant professor in the UGA College of Engineering, explained how his team manipulated the biology for human advantage.

Renewable energy is gaining major momentum in Spain. In April, the country set a new record with renewable energy accounting for 54 percent of the electricity generated in Spain. April’s figure just outpaced March’s record of 51.8 percent of electricity generated by renewables. And those numbers should continue to grow, as wind and solar development continues in the Mediterranean country.

As Japan’s Fukushima nuclear disaster demonstrated, no nuclear plant is ever completely safe. In January 2012, the San Onofre nuclear generating station (SONGS) in Southern California was closed due to the discovery of a radiation leak and other damaged components. It has now been over a year, and Southern California Edison (SCE), which operates the station, has asked the Nuclear Regulatory Commission (NRC) for permission to bring the plant back online. Unfortunately for them, a shocking photograph published by local ABC affiliate 10 News has cast doubt over whether SCE’s request should be granted. The image, taken almost a year after the plant’s closure, shows a leaky pipe being held together with masking tape, plastic bags and broom handles.

Urban Green Energy Inc has installed 120 solar and wind-powered streetlights in PingQuan, situated in the Hebei province of China. Instead of opting for costly traditional lights that would have needed to sink wires into the ground and connect to the grid, the city chose a more sustainable route. Each Sanya light is equipped with a HoYi! wind turbine and two 280 watt solar panels, allowing them to function completely off-grid.
