Popeye Was Right: There’s Energy in That Spinach

Newswise — Using a simple membrane extract from spinach leaves, researchers from the Technion-Israel Institute of Technology have developed a bio-photo-electro-chemical (BPEC) cell that produces electricity and hydrogen from water using sunlight. The raw material of the device is water, and its products are electric current, hydrogen and oxygen. The findings were published in the August 23 online issue of Nature Communications. The unique combination of a man-made BPEC cell and plant membranes, which absorb sunlight and convert it into a flow of electrons highly efficiently, paves the way for…

Energy Is at the Core of the Sustainable Development Goals

Access to affordable, reliable and sustainable energy is crucial to achieving many of the Sustainable Development Goals. Sustainable Development Goal 7 is all about saving energy. But why is it so important to think energy efficiency first? Let me start with some context. This week, hundreds of leaders from politics, business and civil society gather in New York for Climate Week. The fact that Climate Week and the United Nations Private Sector Forum are now an annual event along with the World Economic Forum shows the importance and opportunity to…

Big, Quiet Changes in Energy, Pollution Part of Obama’s Legacy

Mostly unnoticed amid the political brawl over climate change, the United States has undergone a quiet transformation in how and where it gets its energy during Barack Obama’s presidency, slicing the nation’s output of polluting gases that are warming Earth. As politicians tangled in the U.S. and on the world stage, the U.S. slowly but surely moved away from emissions-spewing coal and toward cleaner fuels like natural gas, nuclear, wind and solar. The shift has put the U.S. closer to achieving the goal Obama set to cut emissions by more…

Three solar energy innovations that could change the world

As the surge in sustainable energy continues, solar power is spearheading the market – making room for new, innovative platforms In 2014, the International Energy Agency stated that the sun could be the world’s largest source of electricity by 2050. Renewable energy start-ups have taken advantage of this gap in the market, launching innovative platforms for solar energy. Any innovation in the renewable sector is a win-win: companies generate revenue, consumers can buy into a cheaper source of energy, and clean energy continues to grow – supporting the green movement….

Renewable power – can it push nuclear out of the picture?

The dominant theme of my articles over the past few years is that despite the multitude of issues surrounding nuclear power, it still has a fantastic opportunity to play a substantial role in world energy supply over this century. Nevertheless, it is unlikely to achieve its potential because too many advocates are resting on their laurels, hoping concerns over climate change will suffice to prompt the long-mooted “nuclear renaissance”. In consequence, they are failing to address the key weakness – namely the need to overcome the fear factor that surrounds…

Why a newsletter on sustainable energy

Most of us know the piramid of Maslow on the hierarchy of needs. Energy is on the base level. Way back, when we still lived in caves we discovered fire. Fire gave us warmth, light and protection. With wood as primary source of energy we where provided in all those needs. Since then energy is one of our primary needs and has grown more and more important by our own development. Where our usage of energy has exploded since the industrial revolution, new energy sources had to be found. Coal and…
