The world uses little more than one percent of the sun’s energy for our electricity needs. A major obstacle to tapping into its full potential is that it is intermittent. Solar fuels could one day store, transport and use solar energy to produce electricity and replace fossil fuels in vehicles.
Many economists and policy experts believe carbon pricing is the most effective way to deal with global warming. But others argue that carbon pricing is not a silver bullet for dealing with climate change. Here’s why.
Most economists and policy experts agree that the most effective and cheapest way to curb the carbon dioxide emissions that are warming the planet is to “put a price on carbon.” How effective are carbon taxes and cap and trade programs?
An Earth Institute pilot project has brought smart solar power to farmers in Senegal, making agriculture more efficient, economical and sustainable.
The outcome of this year’s presidential election could have far-reaching implications for the fate of our planet because the two presumptive candidates, Democrat Hillary Clinton and Republican Donald Trump, have very different ideas about climate change. What will they do about the Paris accord and climate change?
Buildings account for almost a third of global greenhouse gas emissions and the U.N. Environment Programme projects that if we continue with business as usual in the building sector, these emissions will double by 2030. Fortunately, green building is on the rise around the world.
Global per capita fish consumption has almost doubled in the last 50 years. And today, about half of all the seafood we eat is produced through fish farming, aquaculture. Can it be done sustainably?
Air pollution, both outdoors and indoors, causes millions of premature deaths each year. The deaths are mainly caused by the inhalation of particulate matter, especially black carbon. But black carbon not only has impacts on human health, it also affects visibility, harms ecosystems, reduces agricultural productivity and exacerbates global warming.
Many experts agree that the climate pledges made at COP21 alone will not hold global temperatures below 2˚ C—we also need significant investment in energy technology innovation in order to meet the climate goals. What are the five big tech companies and their founders doing about climate change?
The new global environmental report card is out. The 2016 Environmental Performance Index graded 180 countries on how well they are protecting human health and their ecosystems. While the world is making progress in some areas, it is seriously falling behind in others.
