Less Coal and More Solar Proposed in Xcel Agreement
A proposal that would lead to the closing of two Pueblo coal plants a decade earlier than planned is before the Colorado Public Utilities Commission, after COSEIA joined with 13 other groups and Xcel Energy asking that the plan be considered. If approved, it could lead to $2.5 billion in clean energy investments in rural Colorado and up to 700 megawatts more solar energy. COSEIA had extensive discussions with members about the proposal because the plan is to pay for the early coal plant retire [...]

Atomic Movies May Help Explain Why Perovskite Solar Cells Are More Efficient
In recent years, perovskites have taken the solar cell industry by storm. They are cheap, easy to produce and very flexible in their applications. Their efficiency at converting light into electricity has grown faster than that of any other material — from under four percent in 2009 to over 20 percent in 2017 — and some experts believe that perovskites could eventually outperform the most common solar cell material, silicon.  [...]

Solar Power: More than half of utility-scale solar photovoltaic systems track the sun through the day
The electricity generated by a solar photovoltaic (PV) system depends on the orientation and tilt of the PV panels, and in some cases, its ability to track the sun throughout the day. Because photovoltaic panels operate more efficiently when oriented directly at the sun, some systems use solar-tracking technology to increase electricity generation by rotating the panels along one or two axes. [...]

8 Benefits of Distributed Solar that Prove it’s Worth More than Dollars and Cents
In October, Environment America Research & Policy Center showcased Shining Rewards, a new review of 16 value-of-solar studies from around the country. The report shows what we already know intuitively: Solar panels provide pollution-free energy that delivers far reaching benefits to people, the environment, the economy, and the electric grid. [...]
