The amount of voluntary renewable energy purchases keeps rising

The amount of renewable electricity being bought voluntarily has increased nearly 300% since 2010, according to new data from the Energy Department’s National Renewable Energy Laboratory.

Why it matters: The trend reflects the increasing availability and affordability of wind and solar electricity, energy sources that have grown from almost nothing a decade ago to nearly 9% of all electricity today.

By the numbers: In 2018, 134 million megawatt hours of renewable electricity — mostly wind and solar — were purchased above and beyond state-level mandates. That's about 3% of all electricity sales in the U.S.

One level deeper: Companies, led by Big Tech firms, are the biggest buyers of the power, but 75% of all customers are actually individuals buying tiny amounts of electricity.

A growing chorus of companies mostly unknown to the wider public is seeking to convince people you don’t need solar panels on your roof to go green.

The intrigue: Instead of writing about this from afar, I’m experiencing it firsthand and sharing my experience. I have signed up with Arcadia Power, a DC-based startup founded in 2014 that’s leading this sector with a digital focus.

IEA hails offshore wind for battling global carbon emissions

Offshore wind power is poised to grow rapidly and fill an important role in the world's renewable electricity mix, a new International Energy Agency report found.

What’s new: Although offshore wind provides just 0.3% of global electricity today, IEA predicts within about two decades it will increase at least 15-fold and make up between 3.1% to 5.4%, depending on how aggressively countries enact policies to cut greenhouse gas emissions.
