NASA is funding projects with the potential to slash airplane greenhouse gas emissions by 75 percent. The agency is targeting airline emissions, a major source of greenhouse gases. NASA last week announced that it was funding research into five new technologies under a “green aviation” initiative that it says could cut airplane fuel use in half, reduce aircraft noise, and most important, slash carbon emissions by as much as 75 percent.

With drought, economic instability, erratic weather and interruptions in transportation a very real threat, it really doesn’t take much to have the food supply disrupted. As the famous proverb says: “Necessity is the mother of invention.” Taking this proverb and running with it, a team of innovators from Quebec, Canada have developed an eco-friendly and exceptionally cost-effective solution to our food woes — The Greenhouse of the Future. Combining the principles of Earthships, aquaponics and passive solar greenhouses, Gendron — along with friends, Christian Désilets and Curt Close — designed and built a radically different food growing system. Not wholly surprising, they christened it The Greenhouse of the Future.

Construction on new buildings never stops, and with it grows a demand of sustainability options. Green construction depends on using the best materials that meet both strength and usefulness as much as it does environmental standards. There is an expected growth of green construction in demand of 11 percent in the next year, so it’s best to understand how and what’s making this happen.

Helena Norberg-Hodge, widely regarded as one of the most significant environmentalists of our time, has been a steady critic of the destructive impact of global monoculture. In addition, she is a pioneer of the “new economy” movement, which promotes localization in the face of a global political economy dominated by money, commercialism and the exploitation of resources for the maintenance and reproduction of capital accumulation.

A group of scientists joined forces to craft a kind of living battery, which they call a bionic leaf for its melding of biology and technology. The device uses solar electricity from a photovoltaic panel to power the chemistry that splits water into oxygen and hydrogen. This bionic leaf converts CO2 in the air into alcohol that can be burned as fuel.

16-year-old climate activist Xiuhtezcatl Martinez is petitioning the 2016 U.S. presidential candidates to take a strong stance on ending climate change. In a Care2 petition and a corresponding video letter, Martinez is urging the candidates to pledge to end fossil fuel use in the U.S. by 2026. The petition attracted over 100,000 signatures in its first week online.

The salt-water powered car was recently approved in Europe. It works just like a hydrogen fuel cell except that the liquid used for storing energy is saltwater. This technology among others, are paving the way for clean green alternative fuel that have a serious potential to replace petroleum in many cases.

As renewables become cheaper to use, many countries are starting to make the switch. The popularity of solar technology in particular has led to some interesting innovations as some countries are now pushing to place solar panels in roads or walkways to both capitalize on the energy of the sun and promote a greener environment.
