On Thursday, the National Wild Horse and Burro Advisory Board recklessly voted to approve recommendations that call on the Bureau of Land Management to shoot tens of thousands of healthy wild horses and burros.
At its meeting in Grand Junction, Colorado, the advisory board recommended that BLM achieve its on-range population goal of 26,715 wild horses and burros while also phasing out the use of long-term holding facilities—both within three years.
If Congress allowed BLM to follow through on the independent board's recommendations, that would mean the government shooting at least 90,000 healthy animals. The advisory board has no power to control policy.
The board also called for allowing international adoptions and sales, which have not been allowed before. During its deliberations, the board repeatedly referenced a proposal made by a private party to have American taxpayers pay to ship upwards of 20,000 wild horses to Russia—where they would serve as prey animals for big cats.
"Killing tens of thousands of wild horses and burros would be a betrayal of millions of taxpayers who want wild horses protected as intended in the 1971 Wild Free-Roaming Horses and Burros Act and who have invested tens of millions of dollars in their care," said Neda DeMayo, president of Return to Freedom Wild Horse Conservation.
"BLM has been tasked by Congress with the responsibility of protecting wild horses. The agency has failed over and over, wasting time on think tanks, challenge concepts and meetings that go nowhere instead of directing resources toward actually managing land, water and habitat on the range and building a robust volunteer effort to help with critical projects benefiting wild horses and other wildlife."
BLM has been close to its Appropriate Management Level before, but the agency balked at using fertility control despite ample evidence that it was safe and effective. The number of wild horses on the range stood within 1,071 animals of BLM's own population goal in 2007, yet even then the agency chose not to aggressively implement fertility control.
In fact, BLM has never spent as much as four percent of its Wild Horse & Burro Program budget on this safe, proven and humane solution for wild horse population control; instead, it spends upwards of 65 percent of its annual budget capturing, removing and warehousing animals.
Return to Freedom's American Wild Horse Sanctuary was among the first of many projects to use fertility control with great success. It has used the vaccine PZP for 19 years with an efficacy rate of 91 to 98 percent.
Meanwhile, wild horses continue to be dramatically outnumbered on federal land by privately owned livestock, which graze there at a fraction of the cost that ranchers would pay on private property.
"A balance must be struck between ranching and mining interests and wild horses and other wildlife as part of a fair interpretation of BLM's multiple-use mandate on the range," said DeMayo. "There needs to be a fairer distribution of resources—not more biased reports and recommendations aimed at capturing, removing or killing wild horses.
"BLM and the U.S. Department of the Interior must stop catering to those who profit from public lands and manage them for all Americans. It is time to stop treating America's wild horses and burros like an unwanted invasive species and start becoming real stewards by using the safe, proven and humane tools available, in keeping with the spirit of the Act and the will of the public."
Polls have repeatedly shown that about 80 percent of Americans oppose horse slaughter and a similar percentage want to see wild horses protected.
A March 1 BLM estimate—made before this year's foal crop—placed the on-range population of wild horses and burros at 72,674. As of August, the agency reported that 44,640 captured wild horses and burros were living in off-range facilities, including 32,146 on leased pastures referred to as long-term holding.
On Thursday, wild horse advocate Ginger Kathrens of the Cloud Foundation was the lone dissenting vote on recommendations that BLM achieve "Appropriate Management Level" of 26,715 in three years, close long-term holding in three years, and allow international sales and adoptions. She joined the others on the board in voting to recommend that BLM increase its funding of reversible fertility control to $3 million by fiscal year 2019, up from about $100,000 in 2017.
Kathrens noted that BLM's arbitrarily set Appropriate Management Level is only about 1,000 wild horses and burros more than the estimated population at the time of the Wild Free-Roaming Horses and Burros Act was signed. The law—which Congress passed unanimously—stated that wild horses and burros were "fast disappearing from the American scene."
The advisory board's recommendation would have BLM spend money saved on long-term holding on on-range management and increasing adoptions. Those adoptions would likely spare only a fraction of wild horses on the range or in holding from death. In 2017, BLM has adopted out only about 4,200 wild horses—its best total in years.
In September 2016, the advisory board voted to recommend destroying captive wild horses and removing all restrictions to their sale, which would allow buyers to purchase them on the cheap and transport them to Canada or Mexico for slaughter. Again, Kathrens was the lone "no" vote.
In July, the House Appropriations Committee approved an amendment to the Interior Appropriations bill that removed language that would bar BLM from killing healthy wild horses. The Senate Appropriations Committee could vote on its version of the Interior bill as soon as next week.
"It will take time, commitment and diligence—and a real plan—but we have science that clearly shows the path to a sustainable future for wild horses and burros," DeMayo said. "It's not going to happen overnight, but it must be done and it must start now. The American people need to rally and urge Congress to force BLM to humanely manage these iconic, federally protected animals on the range."
Solar panels allow you to harness the sun's clean, renewable energy, potentially cutting your electric bills as well as your environmental footprint. But do solar panels work on cloudy days, or during seasons of less-than-optimal sun exposure? For homeowners who live outside of the Sun Belt, this is a critical question to consider before moving ahead with solar panel installation.
In this article, we'll go over how solar panels work on cloudy days, whether solar panels work at night, and how to ensure you always have accessible power — even when your panels aren't producing solar energy.
How Solar Panels Work on Cloudy Days
Photovoltaic (PV) solar panels can use both direct and indirect sunlight to generate electrical power. This means they can still be productive even when there is cloud coverage. With that said, solar panels are most efficient and productive when they are soaking up direct sunlight on sunny days.
While solar panels still work even when the light is reflected or partially obstructed by clouds, their energy production capacity will be diminished. On average, solar panels will generate 10 to 25% of their normal power output on days with heavy cloud coverage.
With clouds usually comes rain, and here's a fact that might surprise you: Rain actually helps solar panels work more effectively. That's because rain washes away any dirt or dust that has gathered on your panels so that they can more efficiently absorb sunlight.
Do Solar Panels Work at Night?
While solar panels can still function on cloudy days, they cannot work at night. The reason for this is simple: Solar panels work because of a scientific principle called the photovoltaic effect, wherein solar cells are activated by sunlight, generating electrical current. Without light, the photovoltaic effect cannot be triggered, and no electric power can be generated.
One way to tell if your panels are still producing energy is to look at public lights. As a general rule of thumb, if street lamps or other lights are turned off — whether on cloudy days or in the evening — your solar panels will be producing energy. If they're illuminated, it's likely too dark out for your solar panel system to work.
Storing Solar Energy to Use on Cloudy Days and at Night
During hours of peak sunlight, your solar panels may actually generate more power than you need. This surplus power can be used to provide extra electricity on cloudy days or at night.
But how do you store this energy for future use? There are a couple of options to consider:
You can store surplus energy in a solar battery.
When you add a solar battery to your residential solar installation, any excess electricity can be collected and used during hours of suboptimal sun exposure, including nighttime hours and during exceptionally cloudy weather.
Batteries may allow you to run your solar PV system all day long, though there are some drawbacks of battery storage to be aware of:
- It's one more thing you need to install.
- It adds to the total cost of your solar system.
- Batteries will take up a bit of space.
- You will likely need multiple batteries if you want electricity for more than a handful of hours. For example, Tesla solar installations require two Powerwall batteries if your system is over 13 kilowatts.
You can use a net metering program.
Net metering programs enable you to transmit any excess power your system produces into your municipal electric grid, receiving credits from your utility company. Those credits can be cashed in to offset any electrical costs you incur on overcast days or at night when you cannot power your home with solar energy alone.
Net metering can ultimately be a cost-effective option and can significantly lower your electricity bills, but there are a few drawbacks to consider, including:
- You may not always break even.
- In some cases, you may still owe some money to your utility provider.
- Net metering programs are not offered in all areas and by all utility companies.
Is Residential Solar Right for You?
Now that you know solar panels can work even when the sun isn't directly shining and that there are ways to store your energy for times your panels aren't producing electricity, you may be more interested in installing your own system.

FAQ: Do Solar Panels Work on Cloudy Days?
How efficient are solar panels on cloudy days?
It depends on the panels, but as a rule of thumb, you can expect your solar panels to work at 10 to 25% efficiency on cloudy days.
How do solar panels work when there is no sun?
If there is literally no sunlight (e.g., at night), then solar panels do not work. This is because the photovoltaic effect, which is the process through which panels convert sunlight into energy, requires there to be some light available to convert.
However, you can potentially use surplus solar power that you've stored in a battery. Also note that solar panels can work with indirect light, meaning they can function even when the sun is obscured by cloud coverage.
Do solar panels work on snowy days?
If there is cloud coverage and diminished sunlight, then solar panels will not work at their maximum efficiency level on snowy days. With that said, the snow itself is usually not a problem, particularly because a dusting of snow is easily whisked away by the wind.
Snow will only impede your solar panels if the snowfall is so extreme that the panels become completely buried, or if the weight of the snow compromises the integrity of your solar panel structures.
Will my solar panels generate electricity during cloudy, rainy or snowy days?
Cloudy days may limit your solar panel's efficiency, but you'll still be able to generate some electricity. Rainy days can actually help clean your panels, making them even more effective. And snowy days are only a problem if the snow is so extreme that the panels are totally submerged, without any part of them exposed to the sun.
