Producing thin-film solar modules requires much less energy than conventional wafer-based Si PV modules, and therefore their energy payback time is much shorter. Chalcopyrite-structured compounds of copper, indium, gallium, and selenium (CIGSe) are an important class of materials for thin-film PV, because CIGSe absorbs incident light much better than silicon, and so a very thin […]
The need to efficiently harvest solar energy for a more sustainable future is increasingly becoming accepted across the globe. A new family of solar cells based on perovskites – materials with a particular crystal structure – is now competing with conventional silicon materials to satisfy the demand in this area. Perovskite solar cells (PSCs) are […]
In the five years since the 17 United Nations Sustainable Development Goals were adopted, many large companies have paid them substantial lip service — declaring support for specific subsets and drawing creative, often detailed maps that demonstrate how certain pieces of the social agenda dovetail with their own larger sustainability and corporate social responsibility goals. […]
At the start of this new decade, American cities, states and businesses already have come a long way on the road to cutting greenhouse gas emissions to help tackle the climate crisis: This puts these subnational U.S. actors on pace to reduce emissions 25 percent below 2005 levels by 2030. To make the transition to […]

Last summer, the Amazon rainforest was in the news again for all the wrong reasons. Deforestation rates are on the rise under the leadership of Brazilian President Jair Bolsonaro and 2019 brought the highest number of forest fires in almost a decade. For the global climate, this is a cause for concern. The Amazon plays […]
Cars Published on February 13th, 2020 | by Years of Living Dangerously February 13th, 2020 by Years of Living Dangerously By Vernon Church It’s easy to become overwhelmed with the climate crisis. With powerful political forces and traditional energy businesses pushing hard to deny the problem, delay progress, or greenwash their own activities, it can […]
The leader of the federal opposition has downplayed the prospects of a cross-bench bill to commit Australia to a target of net-zero emissions by 2050, saying there was little chance it would gain bipartisan support. In an interview on ABC radio Labor’s Anthony Albanese said that while the legislation proposed by Independent MP Zali Steggall […]
