U.S. solar power has dropped a whopping 70 percent since 2009, even as panels get smarter.

Solar Energy Sees Eye-Popping Price Drops

New EIA analysis shows nukes don’t help reduce carbon emissions under EPA’s Clean Power Plan

In other words, increased investment in nuclear power means decreased investment in cleaner solar power. We can have a nuclear future or we can have a solar future: we can’t have both. And a solar future is cleaner, cheaper and safer.

And, as analyzed by Utility Dive, perhaps the most significant finding is that nuclear power does not help achieve greater carbon emission reductions.

Benefits of Green Roofs

There are so many benefits to green roofs. Here are just a few:

  • Adding natural beauty and major aesthetic improvement to buildings, which in turn increases the investment opportunity.
  • Helping contribute to landfill diversion by prolonging the life of waterproofing membranes, using recycled materials, and prolonging the service of heating, ventilation, and HVAC systems through decreased use.
  • Green roofs assist with storm water management because water is stored by the substrate, then taken up by plants, and thus returned to the atmosphere through transpiration and evaporation. They also retain rainwater and moderate the temperature of the water and act as natural filters for the water that does run off. They delay the time at which runoff occurs, which results in decreased stress on sewer systems during peak periods.
  • The plants on green roofs do a great job of capturing airborne pollutants and other atmospheric deposition. They can also filter noxious gasses.
  • They open up new areas for community gardens, commercial and recreational space in busy cities where this space is generally quite limited.

Solar and Wind Energy Start to Win on Price vs. Conventional Fuels

The New York Times:

The cost of providing electricity from wind and solar power plants has plummeted over the last five years, so much so that in some markets renewable generation is now cheaper than coal or natural gas.

So let me add: fuck you nuclear, and your malignant, cancerous apologists. Fuck you gas fracking and the outright poisoning of our vital aquifers. Fuck you oil drillers, destroying the Gulf of Mexico as if it was yours to destroy. Fuck you, fuck you, fuck you.

New study:

Streaming video more ‘green’ than DVDs? Billions of kilograms of carbon dioxide could be saved by scrapping discs, study shows

But this is hardly the only part of the moviemaking industry that is incredibly wasteful. Some efforts at sustainable production may seem trivial at first glance. As cultural leaders, the cutting edge that people naturally look to in their off-hours, the movie industry has a responsibility to promote sustainability.

By simply issuing reusable water bottles and filtering water thousands of plastic bottles can be saved. This practice is good for your home as well.  Water bottles are extremely wasteful and the plastic leaches into your drinking water to boot.

Productions that are green-friendly are demanding LED lighting systems, saving massive amounts of electricity.  Hybrid cars are in wide use, and these should be phased out in favor of electric.

We are an insanely wasteful culture, destroying the natural ecosystems at unprecedented rates.  This should matter to you.

Engineers Design, Test Taller, High-Strength Concrete Towers for Wind Turbines

“What we have shown is that this system can potentially be deployed to a 100-meter height for a 2.5 to 3 megawatt system,” Sritharan said.

Moving from 80- to 100-meter towers is important for wind energy producers.

Sritharan said wind conditions at 100 meters are steadier and less turbulent. Taller towers also allow for longer turbine blades. Studies indicate all of that can increase energy production by 15 percent.
