Don't hold your breath, but future historians may look back on 2015 as the year that the renewable energy ascendancy began, the moment when the world started to move decisively away from its reliance on fossil fuels.
We need an informed dialogue about how local solar power (large-scale and rooftop) can impact low-income communities and communities of color in the U.S. We need to talk about "all the good things, and the bad things, that may be."
India's Prime Minister Modi is dreaming big on solar, aiming to use this clean resource to bring electricity to the 300 million Indians currently living without it. Ambitious as that is, it turns out he's not the only national leader turning to solar to power development.
An innovative American company called All Power Labs has a creative approach to tackling the challenge of energy poverty, one that has turned existing ideas about development aid and manufacturing jobs on their head.
Millions more who become sick with perfectly treatable conditions have no hope of recovery because their hospitals don't have access to electricity. There are no incubators, no life-saving equipment and no refrigeration to store essential vaccines.
Change doesn't always happen swiftly or smoothly, but in a world where people want more control over their entertainment, communication, and transportation, utilities that rely on operating a grid for profits may want to think differently.
It was with great interest that we read this week of two claimed breakthroughs in the area of fusion energy, by the U.S. aerospace company Lockheed Martin and a separate team of Italian and Swedish scientists. We will continue to monitor both of these developments.
Conventional wind facilities on land, while essential for the renewable energy sector, are troubled by the intermittency of wind strength. But offshore wind facilities could offer an efficient means of drawing a highly abundant source of energy.
The way we now use energy in the world -- burning fossil fuels like coal and oil -- is causing our climate to change in ways that are disproportionately hurting the poorest, many of whom are women and children.
Dr. James Hansen, a leading world expert on climate change, has brought me great disappointment. On Nov. 3, 2013, Dr. Hansen decided to support the construction of large numbers of nuclear plants as a way to save the day for climate change.
Upwards of 1.3 billion people across the globe currently lack access to affordable and reliable electricity. Something we take for granted is missing from their lives, with dramatic consequences for human health, education, and economic well-being.
The decisions that all of us make today will definitely impact and decide what the world looks like in the future. A sustainable future can be realized only if the three dimensions of sustainable development work and grow in harmony.
What's a President to do when confronted with killer gas? But let's say that the gas in question threatens the President's own country and that Tomahawk missiles are utterly irrelevant. I refer not to poison gas released in a Damascus suburb, but to greenhouse gases.
Climate change -- and the hotter temperatures that come with it -- only make smog worse. For children, the elderly, outdoor workers, and those without health insurance in the Hispanic community, these conditions can be deadly.
The argument goes, "We've done such a crappy job of caring for our planet that we really do need to look for another place to live." I suppose that's what bugs me about Mr. Hawking's call for more public money for space exploration. It's the rationale.
