Burning Sugar Cane Pollutes Communities of Color in Florida. Brazil Shows There's Another Way.

In Cambodia 2.5 million people use stoves fueled by forest biomass; charcoal and wood. The emissions caused by using biomass are extremely harmful not only to people but also to the environment. The emissions caused by biomass globally are equal to those of the aviation industry. To counter the problem, several organizations and companies are providing alternatives for Cambodian families like electric stoves. One company, Khmer Green Charcoal, created stoves that run on “clean” charcoal made from coconut shells. More than 6,500 households across the country have made the transition.

Scientists at Oxford University have come up with a process that could turn carbon dioxide into jet fuel. The greenhouse gas, which is a major contributor to climate change, is constantly emitted by the aviation industry and this method would allow for that gas to be recycled into a liquid fuel for flights. Scaling the experiment has its challenges, but the process could result in net-zero emissions from airplanes.

Because of a collaborative effort between a high school cross country team and Chispa, an environmental advocacy group, Arizona’s Phoenix Union High School District has bought its first electric school bus. While nearly three times more expensive than a regular school bus, the school district considered the long-term sustainability, not just in terms of fuel and maintenance costs, but in regards to larger, environmental efforts as well.

Researchers in Australia have discovered a way to capture CO2 from the air and turn it back into solid carbon. The new method uses liquid metal and electricity to process the CO2 and store it at room temperature – something that until now had not been possible. Scientists say it shows potential for large scale use – in combination with sustainable energy – as the world continues to grapple with the effects of climate change.

Air pollution is a major health risk, and growing in severity as more of the population moves to urban (more polluted) areas. Several university friends from Germany developed a "CityTree," which filters toxic pollutants from the air with moss that can be installed around cities.

In Virginia, as more and more people turn towards electric cars like Tesla, homeowner associations will have to accommodate resident's request for electric charging stations. Because of that very reason, one legislator created Senate Bill 630, which prohibits homeowner and condominium associations from prohibiting installation in a resident's parking space. This story goes into detail about how one man used SB 630 to get three charging stations installed in his condominium.

Climeworks is focusing on pulling carbon dioxide directly out of the air to store or reuse in some capacity as a way to lower global greenhouse gas emissions. The Swiss company has 16 plants around Europe, with their biggest one in Switzerland that removes 900 tons of carbon dioxide a year that is then sold to Coca-Cola Co. to put in soft drinks or to local industrial greenhouses for plant growth. Scaling the operations to capture more carbon is costly, but the startup recently raised $76 million from investors.

Three major US companies are leading the way in developing the technology to extract carbon dioxide from the air: Global Thermostat, Carbon Engineering, and Climeworks. With federal tax credits per ton of carbon dioxide captured and a prosperous system of injecting the CO2 back into the ground to stimulate crop yield, the companies' three different approaches all offer a way to cut into the massive amount of global emissions, an opportunity to make a lot of money with new technology, and a helping hand for states working on achieving new federal guidelines and restrictions for a green future.

Hydrogen fuel has made promising strides from Germany to Japan, thanks to shifting markets for renewables, improved storage technologies, and emissions-reduction goals. Electrolysis that uses renewables to make the fuel could transform transportation and energy infrastructure, but a few concerns about the unintended effects persist.

An economic shift to renewable energy could take decades, but thanks to rapidly evolving disruptive technologies, dropping prices of solar and wind power sources, and increasing market demand for green business, the new age of renewable energy could encompass the world economy much more quickly.
