Solar Energy and Global Poverty Reduction

One in five people, roughly 1.3 billion globally, do not have access to electricity that would improve health and education while decreasing poverty. In sub-Saharan Africa, the proportion of individuals lacking electricity rises to seven out of 10. Right now, 225 million people in sub-Saharan Africa rely on health facilities that have no electricity, and

Hurricane Harvey: Most fatalities occurred outside flood zones

A Dutch-Texan team found that most Houston-area drowning deaths from Hurricane Harvey occurred outside the zones designated by government as being at higher risk of flooding: the 100- and 500-year floodplains. Harvey, one of the costliest storms in US history, hit southeast Texas on 25 August 2017 causing unprecedented flooding and killing dozens. Researchers at

Portugal is showing that ambitious renewable energy goals are within reach

Portugal's energy system operator had some interesting news to share once March had closed out. It seems that even as Portugal's monthly energy consumption increased 9.7 percent compared to March 2017, the country produced enough renewable energy (just over 4,800Gwh) to exceed its energy demand (just over 4,600Gwh). This doesn't mean Portugal avoided fossil fuel

Canadian Pension Fund Fuels India’s Largest Renewable Energy Deal

Earlier this month, ReNew Power Ventures Limited became India’s largest renewable energy developer following the acquisition of another renewable energy developer. Canadian pension funds had a major role in this landmark transaction. The Canada Pension Plan Investment Board (CPPIB) invested $247 million in ReNew Power to support the acquisition of Ostro Energy. This is the

The Secret To Protecting Places Vulnerable To Climate Change

Individuals living in the most vulnerable areas around the globe are already familiar with the daily effects of climate change, and for small island nations like the Seychelles in the Indian Ocean, the impacts are devastating. Widespread coral die-off from warmer ocean temperatures compounds the issue: As coral reefs die, they are less effective as a

Logging Tropical Forests Jeopardizing Drinking Water

Globally, remaining tropical forests are being rapidly cleared, particularly in countries like the Solomon Islands where commercial logging accounts for about 18 percent of government revenue, and at least 60 percent of exports while providing the largest number of formal sector jobs. However, the loss of native forests has huge ecological and social consequences, many

Removing pharmaceutical residues from wastewater

A doctoral dissertation to undergo a public examination at Lappeenranta University of Technology (LUT) examines  the removal of harmful organic substances, such as pharmaceutical residues, energy efficiently from wastewater using only electricity. According to practical tests, pulsed corona discharge (PCD) may significantly reduce the environmental burden of pharmaceutical residues. According to the pilot tests in

East-west divide between moist and arid parts of U.S. may be shifting

In 1878, the American geologist and explorer John Wesley Powell drew an invisible line in the dirt—a very long line. It was the 100th meridian west, the longitude he identified as the boundary between the humid eastern United States and the arid Western plains. Running south to north, the meridian cuts northward through the eastern states of Mexico, and on to Texas, Oklahoma, Kansas, Nebraska,

The Road Ahead for Solar PV Power

Over the past decade, solar photovoltaic (PV) power has experienced dramatic deployment growth coupled with substantial decreases in system prices. This article examines how solar PV power is currently positioned in the electricity marketplace and how that position is likely to evolve in the foreseeable future. We first assess the current cost competitiveness of solar

An oil-eating bacterium that can help clean up pollution and spills

From pipelines to tankers, oil spills and their impact on the environment are a source of concern. These disasters occur on a regular basis, leading to messy decontamination challenges that require massive investments of time and resources. But however widespread and serious the damage may be, the solution could be microscopic -- Alcanivorax borkumensis --

Ultra-powerful batteries made safer, more efficient

Scientists all over the world -- including even the inventor of lithium ion batteries himself, John Goodenough -- are looking for ways to make rechargeable batteries safer, lighter, and more powerful. Now, an international team of researchers led by Bingqing Wei, a professor of mechanical engineering at the University of Delaware and the director of

Greener and cheaper technique for biofuel production

A team of engineers from the National University of Singapore (NUS) recently discovered that a naturally occurring bacterium, Thermoanaerobacterium thermosaccharolyticum TG57, isolated from waste generated after harvesting mushrooms, is capable of directly converting cellulose, a plant-based material, to biobutanol. A research team led by Associate Professor He Jianzhong from the Department of Civil and Environmental

Pulling valuable metals from e-waste makes financial sense

Electronic waste — including discarded televisions, computers and mobile phones — is one of the fastest-growing waste categories worldwide. For years, recyclers have gleaned usable parts, including metals, from this waste stream. That makes sense from a sustainability perspective, but it’s been unclear whether it’s reasonable from an economic viewpoint. Now researchers report in ACS’

Human-Engineered Changes on Mississippi River Increased Extreme Floods

A new study has revealed for the first time the last 500-year flood history of the Mississippi River. It shows a dramatic rise in the size and frequency of extreme floods in the past century—mostly due to projects to straighten, channelize, and bound the river with artificial levees. The new research, led by scientists at

Portugal generated enough renewable energy to power the whole country in March

Portugal’s renewable electricity production exceeded monthly consumption for what is likely the first time, in March, according to the nation’s transmission system operator, REN. The average renewable generation for the month exceeded 103% of consumption, beating out the last record (99.2%), set in 2014. It almost certainly won’t be the last time. The country is

This is the environmental footprint of the egg industry

In recent years, egg production has been in the spotlight for animal welfare issues. While in most European countries the number of farms with free-range hens increases, in Spain 93% of laying hens are still caged. Added to this are the effects that the industry generates on the environment. A team of Spanish scientists reveals
