Solar Rooftops Looking Better Than Ever
The price for installing solar panels continues to get lower and lower as volumes increase and technology improves. There are also more ways than ever to get solar installed with leases and other creative financial arrangements.
Mandatory Solar In San Francisco
California leads the nation in the use of solar energy with well over half the country’s solar electric capacity. The state is the home of several of the largest thermal solar generating plants in the world and between those and multiple utility-scale photovoltaic plants, California utilities get more than 5% of their power from the sun.
Clean Fossil Fuel Electricity
Renewable energy sources like wind and solar power are getting cheaper all the time and are, in many places, competing head to head on price with traditional fossil fuel generation. The ultimate goal is to replace polluting energy sources entirely, but even under the most optimistic scenarios, fossil fuel plants aren’t just going to disappear very quickly.
Scottish Coal
The Scottish government has an ambitious plan to meet 100 percent of its demand for electricity from renewable sources by 2020. Like much of the world, Scotland has produced significant amounts of its electricity by burning coal for more than 100 years. But no longer.
Coal And Water
We recently highlighted how safe drinking water is in short supply. According to research published in the journal Science Advances, at least two thirds of the global population – more than four billion people – live with severe water scarcity for at least one month every year. And 500 million people around the world face water scarcity all year.
Old-School Companies And Renewable Energy
The biggest Internet companies have been embracing renewable energy for years now. The company that bought the largest amount of clean energy last year was Google, which has three times the renewable capacity of the next biggest user. Other familiar names in the top ten companies in total wind and solar capacity include Amazon, Facebook, Microsoft, and Apple. These companies have been ahead of the pack in looking for sustainable ways to meet their substantial energy needs.

The World’s Largest Solar Plant
Morocco has switched on what is going to be the world’s largest concentrating solar power plant. The plant is located near the city of Ouarzazate, an area previously famous as a filming location for blockbusters like Lawrence of Arabia and Gladiator. When fully online in 2018, the plant will produce enough energy to power over a million homes. It will also cut carbon emissions by 760,000 tons a year.
Solar Roadways
France’s roadways are known both for their historic cobblestone streets and infamous traffic jams. But French officials recently decided to forgo the traditional brick and pavement in order to capitalize on all the vehicle traffic.
Land, Water and Energy
The city of Holtville in California is sometimes called the “Carrot Capital of the World.” This agricultural community has signed an agreement with Australian company Infratech to build a floating solar power system for its water treatment plant.
San Diego Green
While 195 countries reached agreement on reducing greenhouse gas emissions in December, the city of San Diego made a major commitment of its own. Whereas the Paris climate accord is non-binding, San Diego has gone much further.
Community Solar On The Rise
Most Americans are bullish on solar power. However, the majority of Americans are unable to install their own rooftop solar system because either they don’t own the place where they live or because their home is unsuitable for installing solar panels for one reason or another.
Pumped Hydro Storage
There is much talk these days about energy storage. As more and more wind and solar power enters the electrical grid, there is an increasing need to be able to store excess energy and have it available when the wind isn’t blowing or the sun isn’t shining. Much of the talk centers around battery technology, and having storage batteries distributed throughout the grid is the most versatile and widely applicable way to provide storage.
China And Renewable Energy
When it comes to carbon dioxide, three countries are responsible for half of the world’s emissions into the atmosphere: China, the US, and India. On a per capita basis, we are far worse than China, but its population is so huge that that it produces twice as much CO2 as the United States and nearly one-third of the world’s emissions.
Storing Heat From The Sun
We are all familiar with the solar panels that cover an ever-growing number of rooftops as well as large arrays in so-called solar farms. These photovoltaic systems turn sunlight directly into electricity. But they are not the only way to make electricity using the sun.
Businesses Going Solar
The fourth annual Solar Means Business Report is out. It identifies major commercial solar projects and ranks America’s top solar users. Just since the first report came out, the amount of solar power installed by America’s top companies has tripled.
