Small-scale microgrids are increasingly seen as the most promising way to bring electricity to the 1.3 billion people worldwide who currently lack it.
Renewable Energy
Will Tidal and Wave Energy Ever Live Up to Their Potential?
As solar and wind power grow, another renewable energy source with vast potential — the power of tides and waves — continues to lag far behind. But progress is now being made as governments and the private sector step up efforts to bring marine energy into the mainstream
Limits on the Grid
Chris Nelder talks to Mackay Miller, Senior Research Analyst at the Natural Renewable Energy Laboratory, about the limits of renewable energy on the grid.
California Finding New Ways To Extend Benefits Of Solar To Low-Income, Minority Communities
The California legislature has sent a bill to Governor Jerry Brown’s desk that aims to extend the benefits of solar energy to communities that often have no access to clean energy technologies.
The Stuff Problem
How much mined material will we need to build a 100-per-cent renewable world?
Will Renewables Replace Fossil Fuels?
What will it take to reach that threshold and what obstacles and limits do we need to understand as we transition to a truly sustainable energy economy?
10 Successes of the Sustainability Movement to Date
What are some of the successes of the sustainability movement? What exactly can sustainists hang their hats on?
On Energy and Fairness
As part of our current theme on ‘Fairness’, we spoke to Juliet and started by asking her what, for her, does a fair energy system look like?
In Clash of Greens, a Case for Large-Scale Solar Projects
Weaning the U.S. economy off fossil fuels will involve the wide deployment of utility-scale solar power. But for that to happen, the environmental community must resolve its conflict between clean energy advocates and those who regard solar farms as blights on the landscape.
Renewable Energy: Why Emissions and the Economy Don’t Tell the Whole Story
A bragging point for the Clean Power Plan is its flexibility; all currently identified low-carbon energy sources can play a role in state plans, including natural gas, nuclear, hydropower and other renewables.
Undamming Rivers: A Chance For New Clean Energy Source
Many hydroelectric dams produce modest amounts of power yet do enormous damage to rivers and fish populations. Why not take down these aging structures, build solar farms in the drained reservoirs, and restore the natural ecology of the rivers?
Solar Access Warming For Renters
Is your home one of the millions that haven’t been able to get solar because you’re a renter? The good news is that policymakers are starting to look for creative ways to expand solar access.
