Shale gas exploitation in the US has helped cut is greenhouse gas emissions by 11%. A study explores what would happen if this were expanded globally, and the findings challenge conventional wisdom.
New research shows the size of man-made earthquakes is linked to how deep industry wastewater is injected into the ground.

The French president said he would eliminate all coal-fired plants in his country by 2021, while his US counterpart is pushing policies intended to make them more profitable. Either way, the laws of economics will win.
There are concerns about the negative environmental and social impact of fracking in the Karoo.
It is extremely important to monitor local seismic activity before fracking starts to avoid causing harm.
Drilling for water in the Karoo where one major concern from fracking is that groundwater will be affected in the shale gas extraction process.
A vulnerability map could help assess the risks associated with fracking and groundwater which around 300 towns depend on in South Africa's Karoo.

As global demand for energy and mineral supplies increases worldwide, the number of man‑made earthquakes is expected to rise. That increases the importance of understanding connection between the two.
Fracking has led to an increase in truck traffic, one of the reasons for worsening trends on air quality in areas with oil and gas drilling.

The fracking boom has led to a large increase of hydrocarbon emissions in rural areas, reversing some regional air toxics trends.
With all parties backing the fracking ban apart from the Tories, Scotland will have to secure full devolvement for energy if it is to fully realise its ambitions for renewables
There are indications shale gas may be present in South Africa’s Karoo.
South Africa's Karoo region potentially holds shale gas that could transform the energy economy of the country. But given the uncertainties around exploration what's the next logical step?

Overuse of sand for construction and industry is harming the environment and fueling violence around the world. Scientists explain why we need international rules to regulate sand mining and use.
Why protesters should think about putting their feet up.
Six million people in Pennsylvania and neighboring states get their drinking water from the Susquehanna River. Major pollution sources include agriculture, urban development and industry.

America's drinking water infrastructure is aging and needs billions of dollars in upgrades. Two extension educators urge consumers to monitor their water and have it tested if they suspect problems.
South Africa’s Karoo has shale gas and could be the location for fracking exploration.
South Africa has been considering shale gas development in the Karoo region. The gas, will be expensive to explore and extract, will be used as part of the country's energy mix.
Can we mitigate the risks associated with fracking?
From crossing a road to fracking for oil, everything has inherent risks. At best, we can only aim to agree that, on balance, they are contained and justified.
The surge in U.S. oil and natural gas production has transformed the energy picture in the country, but the influence is muted globally.
The Trump administration has set a new national policy: energy dominance. But can the US really dominate other countries through fossil fuel exports?

Oklahoma is trying to limit the number of earthquakes caused by oil and gas extraction, but some existing faults there – which could be activated by wastewater injection – have never been mapped.

The industry has wanted access to offshore oil for decades, but the Arctic remains challenging. Consumers, meanwhile, seem conflicted on expanded offshore drilling.
A false divide between ethics and economics has diluted the immense potential power of the world's biggest sovereign wealth fund.

The federal government seems keen to usher in a new boom in onshore gas production. But gas firms will need to tread carefully, as past experience in Queensland's fracking heartland shows.
California is particularly earthquake-prone, hosting the great San Andreas fault zone.
Can California's wet weather make earthquakes more likely? Scientists are still learning about what triggers these events. Even human activity can be a culprit.
