Why urban farming is changing the future of agriculture

The planet is growing more food than ever, and yet millions of peoplecontinue to starve worldwide. People are hungry everywhere — in the country, in the suburbs. But increasingly, one of the front lines in the war against hunger is in cities. As urban populations grow, more people find themselves in food deserts, areas with “[l]imited access to supermarkets, supercenters, grocery stores, or other sources of healthy and affordable food,” according to a report by the U.S. Department of Agriculture.

Gobierno expide decreto que regula la Gestión Integral de los Residuos de Aparatos Eléctricos y Electrónicos

Bogotá D.C. Febrero 20 de 2018. (MADS). El Gobierno Nacional entrega una nueva herramienta al país para afrontar la problemática ambiental que representa la generación creciente de Residuos de Aparatos Eléctricos y Electrónicos y su disposición final inadecuada. Es el Decreto 284 del 15 de febrero de 2018, que junto con la promulgación de la “Política Nacional para la Gestión Integral de los RAEE“, en el 2017, representa un avance en la regulación de la Gestión Integral de los Residuos de Aparatos Eléctricos y Electrónicos (RAEE) en el país.

Making the right battery storage choice for solar panel installations

Battery storage used in solar panel installations is increasingly complex yet also becoming indispensable. It has emerged as a complement to solar energy, diverting energy to the batteries when production is higher than consumption. This energy is then available for use when energy consumption is higher than energy generated. As a result, batteries can have an important role in determining the amount of energy purchased from a utilities company or preventing outages on a microgrid.

Charging ahead: how Australia is innovating in battery technology

Lithium-ion remains the most widespread battery technology in use today, thanks to the fact that products that use it are both portable and rechargeable. It powers everything from your smartphone to the “world’s biggest battery” in South Australia. Demand for batteries is expected to accelerate in coming decades with the increase in deployment of electric vehicles and the need to store energy generated from renewable sources, such as solar photovoltaic panels. But rising concerns about mining practices and shortages in raw materials for lithium-ion batteries – as well as safety issues – have led to a search for alternative technologies.
