Featuring Peter W. Davidson, CEO and co-founder of Aligned Intermediary; and Nate McMurry, ’10BUS, vice president, divestiture and portfolio management at EDF Renewable Energy, this panel discussed how capital and investing is flowing into clean energy and renewables, creating opportunities for technology to be scaled to address the growing energy needs of society.

This session was moderated by Bruce Usher, co-director of the Tamer Center for Social Enterprise; Elizabeth B. Strickler ’86 and Mark T. Gallogly ’86 Faculty Director; and Professor of Professional Practice at Columbia Business School.

Go to Avasva webpage if you'd like to know how to build it. Good solutions for everyone I think

we need the skill sets to clean up weaponized nuclear waste

windmills and solar panels will be easily destroyed in superstorms

Some of the points in this video are so BS.
Research and develop renewable energy has become a 'politically correct' trend in many countries, some questions from developing country students just so ignorant, they only see how clean or cheap the renewable energy is, but they ignore the fact why their government stick with coal energy. First, initial implement for renewable energy is much higher than coal energy, second, the available energy output for wind energy is only half of the available energy output of coal energy, coal energy can generate electricity 6000 hours a year, and wind energy can generate 3000 hours maximum. Wind is cheap and more efficient, but you need a lot more to reach the same output level as coal energy.
These three guys sitting there in a God view to answer questions for developing countries, asking them to change coal from wind, however, you have to admit that in many developing countries, changing from coal to renewable is not a short term job. It required a few decades.
The problem is actually still economics, namely the economics of a sustainable energy storage system which is still extremely expensive. Most power on the grid is produced on demand, so academia really has no grasp on the consequences of converting to 100% renewable energy simply because this would require massive energy storage systems and there is no data to study this because no one has done it before. It just doesn’t make sense economically given todays tech.
Thank you for the informative dialogue here.

Why Storage is Key for a Renewable Energy Future The Challenge with Renewable Energy 2 days ago   1:00:00

The Colorado Renewable Energy Society presents:
Ken Regelson & Rhonda Peters:
The GRID needs a BATTERY - Why Storage is Key to a Clean Renewable Energy Economy

Batteries hold the key to a power grid based on clean renewable energy sources but they can do a lot more than most of us know. Learn why we can be optimistic that remaining hurdles in policy, technology and cost will soon be overcome.

Rhonda Peters, PhD, is an energy engineer and Principal at InterTran Energy Consulting. Her background is in the wind industry.

Ken Regelson is an electrical engineer and consultant focussed on accelerating the move to a sustainable energy future. He is online at
