Air Pollution And Solar Power

July 28, 2017 By EarthWise

Air Pollution And Solar Power https://earthwiseradio.org/wp-content/uploads/2017/07/EW-07-28-17-Air-Pollution-and-Solar-Power.mp3

We are well-aware of the negative effects of air pollution on human health and on the environment, but a recent study at Duke University has revealed that global solar energy production is taking a major hit due to air pollution and dust.

Melting Ice Adds Life To The Sea

Melting Ice Adds Life To The Seahttps://earthwiseradio.org/wp-content/uploads/2017/04/EW-05-19-17-Melting-Ice-Adds-Life-to-the-Sea.mp3

The changing climate has many effects upon the world’s ecosystems, some of which are surprising.  One of these relates to the effect of the increasing melting of ice in the Arctic.  The ice melt is leading to more life in the Arctic sea.

A Better Way To Farm Algae

A Better Way To Farm Algaehttps://earthwiseradio.org/wp-content/uploads/2017/03/EW-03-07-17-A-Better-Way-to-Farm-Algae.mp3

Microalgae biofuels may provide a viable alternative to fossil fuels.  Algae efficiently use CO2 and can produce biomass very quickly.  Some species can double their mass in as little as 6 hours.   Such single-celled organisms are amenable to high-throughput techniques to evolve new strains, unlike terrestrial biomass sources like corn which can take years to modify.

Disruptive Light Bulb Technology

Disruptive Light Bulb Technologyhttps://earthwiseradio.org/wp-content/uploads/2016/09/EW-09-27-16-Disruptive-Light-Bulb-Technology.mp3

Investment companies like to talk about the disruptive nature of technologies and how they change industries while simultaneously changing our lives.  The growing emphasis on a low-carbon economy has spotlighted a number of technologies as being disruptive in their industry sectors.  One hears this frequently when discussing wind and solar power.  Clearly, these two technologies are changing the face of the utility industry, but at least at present, they still represent a fairly small fraction of the overall business.

Light Pollution And Early Spring

Light Pollution And Early Springhttps://earthwiseradio.org/wp-content/uploads/2016/08/EW-08-17-16-Light-Pollution-and-Spring.mp3

We have talked about the impact of light pollution on our ability to see stars and the Milky Way.  We have also discussed its impact on our circadian rhythms.   Recently, scientists in Great Britain published a report on the relationship between light pollution and the timing of when trees produce their buds.  The results of the study suggest that light pollution is causing plants to jump the gun on spring.

Light Pollution

Light Pollutionhttps://earthwiseradio.org/wp-content/uploads/2016/06/EW-06-29-16-Light-Pollution.mp3

The luminous glow of the Milky Way, the galaxy that contains our Solar System, has inspired everything from stories and songs to paintings and poems for centuries.  But now one third of the people on the planet – including 80% of Americans and 60% of Europeans – cannot see the Milky Way at night because of light pollution.  Nighttime light pollution now covers nearly 80% of the globe.

Keeping Up With Light Bulbs

Keeping Up With Light Bulbshttps://earthwiseradio.org/wp-content/uploads/2016/02/EW-03-08-16-Keeping-Up-With-Light-Bulbs.mp3

Light bulbs entered people’s lives in the 1880s.  Tungsten filament lightbulbs have been around for about 100 years.  Fluorescent lamps were invented in the 1920s.   These two mainstays dominated most lighting applications for most of the twentieth century.

Arctic Ecosystemshttps://earthwiseradio.org/wp-content/uploads/2016/01/EW-02-11-16-Brighter-Oceans.mp3

Most of us are aware that shrinking ice cover is bad news for Arctic wildlife, with animals like polar bears and seals losing important breeding, nursery, and feeding grounds. What has received less attention is the impact ice loss has on life in Arctic waters. [Read more…] about Arctic Ecosystems
