The researchers measured how many insects were attracted to a range of paint colours, including pure white, light and dark grey, sky blue, red and purple.

They did so by laying out coloured cards in a random sequence next to a 13m-high three-blade wind turbine situated in a meadow near Leicestershire, UK.

The scientists were surprised by what they discovered.

"Our major conclusion from this work is that turbine paint colour could be having a significant impact on the attraction of insect species to the structure, both during the day and at night," Miss Long told the BBC.

What is more, turbines painted pure white and light grey drew the most insects bar just one other colour; yellow.

The insects attracted included small flies (body size less than 5mm); large flies (body size equal to or greater than 5mm); greenfly; moths and butterflies; thrips; beetles and crane flies.

"We found it extremely interesting that the common turbine paint colours were so attractive to insects," said Miss Long.

"Our findings support the hypothesis that turbines may be attractive to insects."

The least attractive paint colour to insects was purple.

That does not necessarily mean that all wind turbines should be painted that colour, say the researchers.

But it does imply that changing a turbine’s colour could have a profound impact on the number of insects it lures in and therefore the number of birds and bats that follow.

The researchers also found that the ultraviolet and infrared components of paint colour, which humans cannot see but insects can, also had a significant impact, with higher levels of both attracting more insects.

Don’t let California Backslide to More Dirty Energy

I just signed the petition “Don’t let California Backslide to More Dirty Energy” and wanted to ask if you could add your name too.

This campaign means a lot to me and the more support we can get behind it, the better chance we have of succeeding.

CNBC spreading climate change denial is another money making opportunity for CREDO

I can see it now: CREDO ginning up more indignation without actually doing something to stop dumbth from festering.

Click and be counted in the fight for our future

We’re on the verge of destroying the balance of the earth so badly that the survival of everything is threatened. World leaders are meeting in just over 100 days to talk climate solutions - this moment needs a massive global day of civic action to force leaders to act and save our future. Join in!

The last ice age happened in 6 months. 6 months for the planet to unleash an army of apartment-building-size ice blocks across Europe and the United States. It was a climate tipping point where the balance is knocked completely out of control and threatens the survival of everything — and three more tipping points exactly like it are on the verge of happening.

It’s our “holy shit” climate moment according to a leading NASA scientist, and only a holy shit massive coordinated day of action response, right now, can change the future we’re facing.

One agreement with common sense steps to end dirty energy can save us. That’s why the UN has called an urgent climate meeting in just over 100 days with all major world leaders — if we greet them on September 20th with the largest ever global climate mobilisation in history we can break through the walls of mega coal, oil, and business that prevent even the best politicians from doing what is right.

There’s no way to get around how big a task this is. But together, each small action will add up into a millions-strong movement that literally drowns out the opposition and gives our leaders the best reason to break free and build a hopeful, clean and green future.

The Associated Press requested data on drilling-related complaints in Pennsylvania, Ohio, West Virginia and Texas and found major differences in how the states report such problems. Texas provided the most detail, while the other states provided only general outlines. And while the confirmed problems represent only a tiny portion of the thousands of oil and gas wells drilled each year in the U.S., the lack of detail in some state reports could help fuel public confusion and mistrust.The AP found that Pennsylvania received 398 complaints in 2013 alleging that oil or natural gas drilling polluted or otherwise affected private water wells, compared with 499 in 2012. The Pennsylvania complaints can include allegations of short-term diminished water flow, as well as pollution from stray gas or other substances. More than 100 cases of pollution were confirmed over the past five years.

Stop the Utility Power Grab

Community Choice energy programs empower local communities to take control of decision-making about the sources and cost of their electrical power. Not-for-profit, democratically controlled Community Choice energy programs enable local governments to reduce greenhouse gas emissions while creating green jobs and stimulating the local economy. These programs are dedicated to reducing consumer electricity demand, providing competitive electricity rates and maximizing the amount of renewable energy in their mix.

In California, Community Choice was made possible by state legislation enacted in 2002. Marin and Sonoma Counties were the first to establish Community Choice programs in 2010 and 2014 respectively. Other counties are currently considering establishing Community Choice programs, including Alameda, San Francisco, Santa Clara, San Diego, Santa Barbara, San Luis Obispo, and Monterey, among others.

In 2008, PG&E spent millions trying (unsuccessfully) to discourage Marin residents from choosing Marin Clean Energy. In 2010, PG&E spent $46 million on an unsuccessful ballot initiative (Prop 16) to change the California Constitution to require a two-thirds majority of voters to establish a Community Choice program. The voters spoke, but PG&E is still trying to kill off Community Choice and preserve its monopoly.

AB 2145 would effectively prevent Community Choice programs from operating anywhere in California. If this bill passes, Californians will be stuck with their dirty energy monopoly utility.

AB 2145 represents a backwards step for California. Don’t let utilities derail our clean energy future!

Urge the EPA to Save Bees

Native pollinators like bees play an essential role in the environment and are an indispensable part of our agricultural system. Many foods that we eat depend on crops pollinated by honeybees and 90% of all flowering plants require pollinators to reproduce. But in recent years, bees and other pollinators have been disappearing at alarming rates, causing widespread concern that these important species could be wiped out altogether.

A widely used class of insecticides called neonicotinoids affects pollinators including honeybees. Since neonicotinoids first became widely used in the mid-2000s, roughly one-third of America’s honeybee colonies have collapsed each year. Allowing even one more of these insecticides to be used on farms and orchards will only make the situation worse.

The U.S. Environmental Protection Agency (EPA) recently approved a new insecticide called sulfoxaflor even though their own scientists considered the product to be similar to neonicotinoids and “very highly toxic” to honeybees. We need to ensure that this insecticide, and others like it, does not get out into the environment. We cannot afford a collapse in pollinator populations.

Urge the EPA to refuse to approve any insecticides unless scientists confirm they present no threat to bees and other pollinators.

Sign the petition: Pass SB 1132 California Fracking Moratorium

I signed a petition to The California State House and The California State Senate which says: "Tell California State Legislators to support a fracking moratorium now and vote yes on SB 1132.”
