Growing Use Of Wind And Solar Power

By Leave a Comment

According to a new report from the U.S. Energy Information Administration, solar and wind energy now generate more than 20% of the electricity used in 10 states.  Topping the list is Iowa, which got 37% of its electricity from wind and solar in 2017.  The next three states were Kansas, Oklahoma, and South Dakota, all getting more than 30% of their power from the renewables.  The top five states, which adds North Dakota to the list, actually get nearly all of their renewable energy from wind.  In fact, during some months in 2017, Iowa and Kansas both got more than half of their electricity from wind.

A Prize For Water From The Air

By Leave a Comment

The XPrize competitions provide monetary incentives to crowdsource solutions to the world’s grand challenges.  Originally started in 1994 to spur the development of private spaceflight, the XPrize program now offers prizes for diverse fields including Oceans, Learning, Health, Energy, Environment, Transportation, Safety and Robotics.

More Power From The Sun’s Heat

By Leave a Comment

When we think of solar power, we usually are talking about the panels that generate electricity using the photovoltaic effect.  These panels are on millions of rooftops around the world and in utility-scale solar farms.   There are also solar water heating systems that use the sun’s heat to provide hot water for homes and businesses.

Microplastics And Humans

By Leave a Comment

Microplastics are everywhere.  The tiny plastic particles pose a massive environmental challenge.  Microplastics are polluting oceans at an alarming rate.  Much of the oceanic microplastics result from the breakdown of plastic litter.  Another source of microplastics pollution is microbeads.  Microbeads, which are commonly added to cleansing and exfoliating personal care products, pollute the environment when they get flushed down the drain.

Fumes From Gas Stations

By Leave a Comment

A study by environmental health scientists at Columbia University examined the release of vapors from gas station vent pipes and found that emissions were 10 times higher than the estimates used to establish setback regulations that determine how close schools, playgrounds, and parks can be to the facilities.

Cloudbursts And New York City

By Leave a Comment

Cloudbursts are intense rainstorms that drop enormous amounts of water over a short period of time.  Climate change is expected to make cloudbursts occur more frequently.  Cities around the world are looking for better ways to cope with weather phenomena like cloudbursts.

Capturing CO2 From The Air

By Leave a Comment

It is increasingly clear that the rate at which carbon dioxide emissions are being reduced is not sufficient to prevent dire consequences of climate change.  It appears that it will be necessary to try to actually remove carbon dioxide from the air.  Such actions are termed “negative emissions.”

Environmental Impact of Wind Power

By Leave a Comment

A recent study by Harvard University researchers published in two papers looked at the environmental impact of installing sufficient wind power to meet all the energy needs of the US.  While doing so would be far better for the environment than burning coal, it would not have negligible impacts.

Electric Buses On The Rise

By Leave a Comment

Electric buses are replacing conventional diesel-fueled buses at an accelerating rate that is outpacing the adoption of battery-powered cars.  According to forecasts by Bloomberg New Energy Finance, by 2030 some 28% of car sales will be electric vehicles while 84% of new buses will be electric buses.  So far, some 12 years away, the actual adoption of electric buses is outpacing this optimistic projection.

Mammals Can’t Seem To Evolve Fast Enough

By Leave a Comment

Our planet has been through five upheavals over the past 450 million years.  During each one, the environment on earth changed so dramatically that most plant and animal species became extinct.  After each of these mass extinction events, evolution slowly filled the gaps in the environment with new species.

Glacial Engineering

By Leave a Comment

As the world struggles with trying to limit carbon emissions and slow the pace of global warming, there is increasing analysis of various forms of geoengineering.   Often, these consist of nearly unthinkable efforts to intervene in the climate on a global scale with unpredictable and possibly catastrophic consequences.
