The absorb about the same amount of light as tinted windows

Over the past few decades, photovoltaic cells have gone from being exotic and expensive power‑packs for satellites and similar high‑end applications to quotidian generating equipment for grid‑scale power stations. One area where they have not yet fulfilled their potential, though, is as local sources of electricity to keep office buildings and the like supplied with energy. The main reason is that no one has a good answer to the question: where do you put them? Roof‑top cells can power a one‑ or two‑storey house. They will not power an office block. You could array them on the walls. But office blocks tend to have high window‑to‑wall ratios and to be governed, for fire‑safety reasons, by strict rules on wall cladding.

What is left is to replace the windows themselves with solar cells. Unfortunately, commercially available solar cells are opaque to the point of blackness. But Seo Kwanyong of the Ulsan National Institute of Science and Technology, in South Korea, plans to do something about that. As he and his colleagues report this week in Joule, they have created solar cells that are as transparent as tinted glass. Den Rest des Beitrags lesen »

Financial institutions must address the issue of technological sustainability, especially with regard to data, robotics, and artificial intelligence. Although these new technologies have vast potential, businesses also need to understand their risks, social impact, and ethical implications.

PARIS – Discussions about “sustainability” usually center on a company’s environmental and social commitments, and for understandable reasons. But the financial sector in particular should consider two other, less obvious, dimensions of sustainability. Regulatory sustainability is essential for addressing the systemic risk that the financial sector poses to our societies. In addition, the emerging new frontier of technological sustainability is having an increasing impact on business models and strategies. Den Rest des Beitrags lesen »

Economic Growth Is the Answer

Michael J. Boskin is Professor of Economics at Stanford University and Senior Fellow at the Hoover Institution. He was Chairman of George H. W. Bush’s Council of Economic Advisers from 1989 to 1993, and headed the so‑called Boskin Commission, a congressional advisory body that highlighted errors in official US inflation estimates. 

While rising inequality – a problem that the data suggest is real but overstated – has moved to the center of public debate, the key issue is that living standards are not improving fast enough among those who are falling behind. It is this fact that is fueling much of the political tension across advanced economies today. Den Rest des Beitrags lesen »
