Going Solar Has Never Been Easier Thanks to Google Earth

It just got a whole lot easier to decide whether or not to get solar panels for your roof. Google's Project Sunroof site will help you locate your home, see how much sun it gets on average and what you could save if you purchased panels.


The project was initially launched in 2015, but has become more popular as solar technology gets more affordable. Google uses a combination of Google Maps, Google Earth and machine learning technology to calculate the sun's path to give an accurate account of your solar situation. It then uses industry standard models to tell you the cost benefit analysis of going solar.

The project is still in progress, but 60 million buildings have been analyzed across 50 states. From that information alone, Google was able to calculate that 79 percent of all rooftops could go solar and in Hawaii, Arizona, Nevada and New Mexico, 90 percent of homes are viable. Houston, Texas has the most viability as a whole with an estimated 18,940 gigawatt-hours of solar generation from rooftops per year.

According to Google, "If the top 10 cities below reached their full rooftop solar potential, they'd produce enough energy to power 8 million homes across the U.S."

Once homeowners see the potential, they can use the site to see how much they will save on their monthly electricity bill based on typical utility rates in their location, as well as annual savings. The site then tells users how much square footage of solar panels to get and how to finance them.

There's even a function to see what an entire community could save should they collectively decide to go solar. For example, in Fresno, California, 92 percent of the rooftops are viable and if they reached full solar capacity, it would be equivalent to taking 261,000 cars off the road each year or planting 31 million trees.

It's still a common misconception that solar is too expensive or that an area doesn't get enough sunny days. Now, homeowners can see for themselves what their potential is and make a more conscious decision about where their energy comes from.

Desperate Puerto Ricans Are Drinking Water From Hazardous Waste Sites

The ranking Democrat on the House Homeland Security Committee called for an investigation into the availability of potable water in Puerto Rico following reports Friday that residents are scrounging for water from hazardous waste sites.

After the U.S. Environmental Protection Agency (EPA) confirmed residents were trying to access water from three Superfund sites, and following a CNN story Friday featuring Puerto Ricans taking water from a fourth site, Rep. Bennie Thompson (D-MS) wrote a letter to acting DHS Secretary Elaine Duke asking if she knew about the situation and calling the reports "beyond disturbing."

Groups Slam Zinke's 'Backroom Deals' to Build Road Through Alaskan Wildlife Refuge

Ryan Zinke's Interior Department is working behind the scenes to build a controversial and long-contested road through the heart of Alaska's Izembek National Wildlife Refuge, documents show.

The refuge was established more than 30 years ago to conserve wetlands and habitats for migrating birds, brown bears and salmon and other wildlife. 300,000 of its 315,000 acres has been designated as Wilderness in 1980 under the Alaska National Interest Lands Conservation Act.

On World Food Day, Pope Francis Says Link Between Climate Change and Hunger Is Undeniable

By Andrew McMaster

Speaking at the United Nations Food and Agriculture Organization (FAO) on World Food Day, Pope Francis addressed the need for governments around the world to acknowledge that climate change and migration were leading to increases in world hunger.

Francis received a standing ovation after a stirring speech in which he said all three issues were interrelated and require immediate attention.

Why Are America's Bats Disappearing?

By John R. Platt

It's Friday evening in Pittsburgh, and the mosquitoes are out in force. One bites at my arm and I try to slap it away. Another takes the opportunity to land on my neck. I manage to shoo this one off before it tastes blood.

I'm at Carrie Furnaces, a massive historic ironworks on the banks of Pennsylvania's Monongahela River. Stories-tall rusting structures loom all around me, as do the occasional trees poking their way out of the ground. A tour guide, leading a group from the Society of Environmental Journalists conference, tells me the soil here is full of heavy metals and other pollutants from the factory, which operated for nearly a century before closing in 1982.

After a Half-Century, Tigers May Return to Kazakhstan

Wild tigers may be on their way back to Kazakhstan.

This news is surprising for a few reasons. First, most people associate tigers with the jungles of India or Sumatra, even the snowy slopes of eastern Russia—not the dry landscapes of Central Asia. But Iran, Turkey and Kazakhstan were once home to thriving populations of Caspian tigers. Unfortunately, sometime between the 1940s and '70s, this subspecies went extinct due to widespread trapping, hunting, poisoning and habitat degradation.

Second, Kazakhstan isn't a nation that often comes up in conversations about conservation. In fact, if Americans recognize the world's largest landlocked nation for anything, it's probably the movie Borat.

UN Urges World Leaders to Heed Climate Risk, Warns of More Severe Disasters

By Paul Brown

The hurricanes and wildfires that have severely damaged large areas of the U.S. in recent weeks have had no impact on President Donald Trump's determination to ignore the perils of climate change and support the coal industry.

In a deliberate denial of mainstream science, the Trump administration has issued a strategic four-year plan for the U.S. Environment Protection Agency that does not once mention "greenhouse gas emissions," "carbon dioxide" or "climate change" in its 48 pages.
