The United States has an energy efficiency ranking of #1, the highest it’s ever been.
The rankings are based on a metric that uses energy efficiency ratings from various sources, including electricity-generation capacity, electricity-consuming appliances, consumer electricity use, vehicle miles traveled, and energy use per capita.
As we know, most of the US population lives in cities.
But in the last decade, the US has seen an explosion in residential energy use.
In 2010, the United States averaged 1,933 megawatts of power generated from the sun, compared to just 929 megawatts in the 1980s, according to the US Energy Information Administration.
The US also has a big problem with urban areas.
We’re not the only nation that has seen a rapid rise in urban electricity consumption, with energy consumption in the US climbing by over 5,000 megawatts per day over the last 10 years, according a report from the US Department of Energy.
But the biggest growth in residential electricity use has been in the Southwest.
According to the report, in 2015, the average residential customer used 1,058 megawatts from the solar panels they installed on their homes.
That’s an increase of 665 megawatts over the previous year.
That makes it the nation’s second-largest source of power generation from solar panels, after the West Coast, and its third-largest energy user after the Midwest and Midwest-based Midwest Solar Power Association.
It’s no wonder the Southwest has such a big role in the nation.
It’s where solar power is used most frequently and most of that electricity comes from rooftop solar installations, the report found.
Solar panels are often built with low-cost materials like aluminum, and they’re often cheaper to install than conventional solar panels.
They can be cheaper to maintain than traditional photovoltaic systems, and the panels have a shorter life cycle than traditional panels.
There’s a lot of data that shows that solar is one of the best ways to reduce our dependence on fossil fuels, said Andrew Schuster, senior director of energy and environmental policy at the Sierra Club.
And while there are plenty of other options for energy efficiency in homes, there are many ways to achieve that, Schuster said.
“There are ways that you can go about reducing energy use without making any changes to your lifestyle,” he said.
“But we’re really talking about the best of both worlds.”
As the United Kingdom’s new Prime Minister Theresa May said last week, solar power can be a “game changer” for our energy security.
A new report from researchers at the University of Wisconsin found that if we could get 100% of our power from solar, it would cost the UK an extra £3.5 billion ($5.2 billion) a year.
And that’s if the country were able to implement its plans to phase out fossil fuel subsidies.
While there are still many hurdles to getting 100% renewable energy, the country is now on track to achieve 100% by 2030, according the United Nations Environment Program.
Last month, the Obama administration announced its new “Renewable Fuel Standard” for electricity, which would require utilities to buy at least 90% of their electricity from renewable sources.
The goal is to achieve 80% of electricity from renewables by 2030.
By 2020, the U.S. will have reached 80% renewable power.
And as we head into a new solar boom, the nation is expected to have an extra 25 gigawatts of solar capacity installed by 2020.
For more on solar, watch: But even without the renewables, the number of Americans without electricity is rising.
The U.N. Population Division says that between 2016 and 2020, more than 7 million Americans lacked access to electricity, according
