This is what's REALLY holding back wind and solar

Alternative Energy No Comments »

Building solar farms and wind parks is one thing. Plugging them into the grid is another. How does our power system need to change to cope with more renewables?

Biomass: How clean is energy from waste and plants really?

Alternative Energy No Comments »

Clean energy from re-growing resources and waste. Biomass sounds like a perfect alternative power source. Globally, at least 5% of energy come from biomass. But what does it mean if we use organic matter for fuel or electricity?

“Wood is one of the few energy sources that emits more carbon than coal.” Burning biomass allowed civilization to evolve and advance in remarkable ways, but smoke that comes as a byproduct is carbon-heavy and kills around 2 million people per year.

How green is solar energy really?

Energy Efficiency No Comments »

More and more solar panels are popping up all over the world – and it’s easy to see why: They provide clean energy at falling prices. Awesome, right? Well actually, there are also some not-so-green sides to this technology. We’ll take a closer look at three big criticisms solar energy faces and check out just how much of a problem they are.

Is California’s Green Energy Really Green? | Michael Shellenberger

The Biden Administration recently announced plans to open more than 250,000 acres off the California coast to wind development as part of a program to expand renewable energy nationwide.

My returning guest today is Michael Shellenberger…described by Time Magazine “as a Hero of the Environment,” also Founder and President of Environmental Progress, and best-selling author of Apocalypse Never: Why Environmental Alarmism Hurts Us All.

Today he discusses why the proposed off shore wind farm, may actually end up harming the environment.
