More Renewables On Campus
We recently talked about the increasing efforts by colleges and universities to embrace sustainability with the use of renewable energy sources. Those efforts are increasing in many places.
Accidental Ethanol From Carbon Dioxide
Scientists at the Oak Ridge National Laboratory in Tennessee were trying to find a series of chemical reactions that could turn carbon dioxide into a useful fuel. But the unexpected occurred: they found that the first step in their process actually got the job done all by itself. The reaction turns CO2 into ethanol, which is already used to power generators and vehicles.
Building A Better Solar Cell
The great majority of solar cells being manufactured today are based on silicon crystals. That technology has come a long way over time and has gotten cheaper and more plentiful as the industry has grown.
Renewables On Campus
Colleges and universities across the country are increasingly deploying solar arrays and other types of renewable energy. Many have set goals to become carbon neutral.
Too Much Of A Good Thing
Germany has continued to be the most aggressive adopter of renewable energy among large industrial nations. The country has the goal of shifting to 100% renewables by 2050. Its continuing embracing of solar and wind generation resources over the past decade has resulted in renewables supplying a third of the country’s power on average.
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.
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.

Big Solar Is Booming
When we think about solar power, we mostly think about rooftops covered with solar panels. And indeed, there are more than 800,000 solar rooftops in the U.S. and the numbers are growing.
Carbon Capture Update
The global community is increasingly making commitments to reduce the amount of carbon emissions in the atmosphere. More and more carbon-free renewable energy sources are being used all the time. But despite the tremendous growth in solar and wind power, fossil fuels still provide about 80% of the world’s energy. Coal still provides about 40% of worldwide electricity. Realistically, these numbers can only go down at a relatively gradual pace.
Ocean Energy Report Card
Most of the world’s activity in renewable energy is focused on solar and wind power. The use of both is expanding rapidly.
