Nebraska Approves Keystone XL, But Requires Different Route Through State

Nebraska regulators have given the final approval for the Keystone XL pipeline to run through their state, eliminating the last major regulatory obstacle preventing the completion of the 1,179-mile pipeline system that would help carry tar sands oil from Alberta, Canada to refineries in Texas.

A new way to store thermal energy

In large parts of the developing world, people have abundant heat from the sun during the day, but most cooking takes place later in the evening when the sun is down, using fuel — such as wood, brush or dung — that is collected with significant time and effort.

USGS Estimates 40 Million Pounds of Potential Uranium Resources in Parts of Texas, New Mexico and Oklahoma

The U.S. Geological Survey estimates a mean of 40 million pounds of in-place uranium oxide remaining as potential undiscovered resources in the Southern High Plains region of Texas, New Mexico, and Oklahoma.

The uranium occurs in a type of rock formation called “calcrete,” which has been well-documented in noted uranium-producing countries like Australia and Namibia. The calcrete formations described in this assessment are the first uranium-bearing calcrete deposits reported in the United States.

Solar Power Rapidly Expands, But So Does Oil Use, in New World Energy Outlook

Solar power will surge globally in the coming decades, but oil demand will also continue to grow, according to a new report from the International Energy Agency.

Learning from Photosynthesis

The green sulfur bacterium makes its home in the chilly waters of the Black Sea. To eek out its lonely existence, this life form scavenges energy from the feeble sunlight available to it at a depth of over 250 feet.

New Routes to Renewables: Sandia Speeds Transformation of Biofuel Waste Into Wealth

A Sandia National Laboratories-led team has demonstrated faster, more efficient ways to turn discarded plant matter into chemicals worth billions. The team’s findings could help transform the economics of making fuels and other products from domestically grown renewable sources.

No more blackouts?

Today, more than 1.3 billion people are living without regular access to power, including more than 300 million in India and 600 million in sub-Saharan Africa. In these and other developing countries, access to a main power grid, particularly in rural regions, is remote and often unreliable.

Increasingly, many rural and some urban communities are turning to microgrids as an alternative source of electricity. Microgrids are small-scale power systems that supply local energy, typically in the form of solar power, to localized consumers, such as individual households or small villages.

Easing the Soil's Temperature

Soil characteristics like organic matter content and moisture play a vital role in helping plants flourish. It turns out that soil temperature is just as important. Every plant needs a certain soil temperature to thrive. If the temperature changes too quickly, plants won’t do well. Their seeds won’t germinate or their roots will die.

JRC at COP23: A Cleaner, Greener Planet is Both Possible and Affordable

Limiting global warming below the critical 2C level set out in the Paris Agreement is both feasible and consistent with economic growth – and the knock-on improvements to air quality could already cover the costs of mitigation measures and save more than 300,000 lives annually by 2030.

We Should Use Central Pressure Deficit, Not Wind Speed, To Predict Hurricane Damage

The system for categorizing hurricanes accounts only for peak wind speeds, but research published in Nature Communications explains why central pressure deficit is a better indicator of economic damage from storms in the United States.

Cities Can Cut Greenhouse Gas Emissions Far Beyond Their Urban Borders

Greenhouse gas emissions caused by urban households’ purchases of goods and services from beyond city limits are much bigger than previously thought. These upstream emissions may occur anywhere in the world and are roughly equal in size to the total emissions originating from a city’s own territory, a new study shows. This is not bad news but in fact offers local policy-makers more leverage to tackle climate change, the authors argue in view of the UN climate summit COP23 that just started. They calculated the first internationally comparable greenhouse gas footprints for four cities from developed and developing countries: Berlin, New York, Mexico City, and Delhi. Contrary to common beliefs, not consumer goods like computers or sneakers that people buy are most relevant, but housing and transport – sectors that cities can substantially govern.

Breaking the Chain: Catalyzing a Green Future for Chemistry

The fight against climate change is a call-to-arms for industry. We currently rely on fossil fuels, a major source of the greenhouse gas CO2, not only for energy but also to create chemicals for manufacturing. To ween our economies off this dependency, we must find a new source of “green” raw materials so that factories and laboratories can run without producing and emitting CO2.

Briny Pool Bacteria Can Clean Up and Power Up

Warm and salty wastewater is a by-product of many industries, including oil and gas production, seafood processing and textile dyeing. KAUST researchers are exploring ways to detoxify such wastewater while simultaneously generating electricity. They are using bacteria with remarkable properties: the ability to transfer electrons outside their cells (exoelectrogenes) and the capacity to withstand extremes of temperature and salinity (extremophiles).

NREL Research Yields Significant Thermoelectric Performance

Scientists at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) reported significant advances in the thermoelectric performance of organic semiconductors based on carbon nanotube thin films that could be integrated into fabrics to convert waste heat into electricity or serve as a small power source.

New Study Suggests the United States' Power Supply Has the Capacity to be More Adaptable to Climate Change than Previously Predicted

Climate change scientists warn that the continued burning of fossil fuels is likely to cause major disruptions to the global climate system leading to more extreme weather, sea level rise, and biodiversity loss. The changes also will compromise our capacity to generate electricity. In recent decades, capacity losses at United States power plants occurred infrequently, but scientists warn that the warming climate may increase their regularity and magnitude. This instability could interrupt power supply to homes, hospitals, transportation systems, and other critical institutions and infrastructure at a potentially high financial cost.

Building a Sustainable Future: Urgent Action Needed

We need to act urgently to increase the energy efficiency of our buildings as the world’s emerging middle classes put increasing demands on our planet’s energy resources. These are the findings of a new report, published in MRS Energy & Sustainability by authors Matthias M. Koebel, Jannis Wernery and Wim J. Malfait.

How cities can fight climate change most effectively

What are the best ways for U.S. cities to combat climate change? A new study co-authored by an MIT professor indicates it will be easier for cities to reduce emissions coming from residential energy use rather than from local transportation — and this reduction will happen mostly thanks to better building practices, not greater housing density.
