Low gasoline prices and continuing performance issues have slowed the growth of electric car sales. But that has not stymied progress in electrifying larger vehicles, including garbage trucks, city buses, and medium-sized trucks used by freight giants like FedEx.
As temperatures rise, the world’s iconic northern lakes are undergoing major changes that include swiftly warming waters, diminished ice cover, and outbreaks of harmful algae. Now, a global consortium of scientists is trying to assess the toll.
On ancestral lands, the Fond du Lac band in Minnesota is planting wild rice and restoring wetlands damaged by dams, industry, and logging. Their efforts are part of a growing trend by Native Americans to bring back traditional food sources and heal scarred landscapes.
Thanks to favorable geography, innovative government policies, and businesses that see the benefits of clean energy investments, California is closing in on its goal of generating a third of its electricity from renewables by 2020.
The main reason soaring greenhouse gas emissions have not caused air temperatures to rise more rapidly is that oceans have soaked up much of the heat. But new evidence suggests the oceans’ heat-buffering ability may be weakening.
With a warmer atmosphere expected to spur an increase in major storms, floods, and other wild weather events, scientists and meteorologists worldwide are harnessing advanced computing power to devise more accurate, medium-range forecasts that could save lives and property.
Promising new technologies, including more efficient photovoltaic cells that can harvest energy across the light spectrum, have the potential to dramatically increase solar power generation in the next two decades. But major hurdles remain.
Desalination has long been associated with one process — turning seawater into drinking water. But a host of new technologies are being developed that not only are improving traditional desalination but opening up new frontiers in reusing everything from agricultural water to industrial effluent.
For two decades, Jack Macy has spearheaded San Francisco’s efforts to become a global leader in recycling. In an interview with Yale Environment 360, he talks about how San Francisco has engaged the public in a recycling crusade that has resulted in the city reusing or composting 80 percent of its garbage.
The emerging field of “energy scavenging” is drawing on a wide array of untapped energy sources — including radio waves, vibrations created by moving objects, and waste heat from computers or car exhaust systems — to generate electricity and boost efficiency.
Still reeling from recent financial crises, Iceland is hoping to use its bountiful sources of geothermal and hydroelectric energy to help boost its economy. Among the country’s more ambitious plans is an undersea cable to carry renewably generated electricity to the U.K.
