#Renewables Buoyant Air Turbine (BAT) from Altaeros will be the highest #windturbine in history. Already tested to 500 feet off the ground in 45 mph winds, this helium-filled shell with a wind turbine in the middle is soon shooting for a world record 1,000 ft float.

The difficulties of maintaining this, similar to the DHS use in the desert for aerial platforms in the SW US, will probably ruin the increased efficiency.  I hope they are successful.

WTI Set for Weekly Gain on Cushing Stockpiles, Ukraine http://qoo.ly/i6v7
West Texas Intermediate headed for a second weekly gain amid shrinking stockpiles at the U.S. oil storage hub in Cushing, Oklahoma. Brent was also poised for a weekly increase as Libyan supply disruptions continued.

I am thinking that most of the top ten renewable electricty producers are getting most of that energy from traditional hydro power.

Last week, the amount of carbon dioxide (CO2) in the earth's atmosphere exceeded 402 parts per million (ppm,) higher than at any time in at least the past 800,000 years, according to the U.S. National Oceanic and Atmospheric Administration. It's time for a #cleanenergy  revolution.

+Zen Benefiel Bio fuels, bio energy or bio CO2 mitigation if very very difficult due to the extremely low efficiency of plants at converting solar radiation to other forms of energy.

Lets look at your example of an acre of kenaf.  Your kenaf converts 10 tons of carbon to carbon compound (so removes the CO2 from the air).  That same acre of land covered with present day PV (efficiency of only 15% or less on average) would produce 3000KWH per day of electricity.  A typical fossil fuel power plant produces about 2lbs of carbon emissions per KWH of electricity.  So an acre of PV panels will effectively eliminate as much carbon emissions in 3 days as an acre of kenaf in a year.

Solar thermal can reach efficiencies of 50-70% (even higher for pool heaters) when producing heat and hot water, so an acre of solar thermal panels can offset as much carbon emissions in one day as an acre of kenaf can in a year.

There are mainly three types of solar tracking technologies based on the system design and engineering:

azimuth tracking, altitude/elevation tracking and our now famous dual axis tracking. See them-- http://toolsforgreenliving.com/solar-trackers-technology/
The use of solar trackers is occasional for flat PV systems as long as the engineer gets the orientation correct. But on concentrated PV systems such as for large commercial energy systems, it’s paramount to include a tracker.

Sustainability targets : are we working on them?

During the last decades, climate change issues have become one of the primary concerns not only for environmentalists, but also for politicians, economists and global shapers.
It is because of this that the following goals were chosen as  part of the  EU  2020 targets :

 1)  greenhouse gas emissions 20% (or even 30%, if the conditions are right) lower than 1990
      2)  20% of energy from renewables
      3)  20% increase in energy efficiency

Are European countries trying to cope with these new targets? How is changing the energy supply? But first of all, is it changing?

Free from worry, free of cost, and the freedom of knowing that they are reducing their ecological footprint. Solar energy contributes to the reduction in green house gas emissions, reduces pollution and produces no waste. In short, solar energy silently and efficiently provides the power to add value to a home, and improve a family's lifestyle.

In the UK, sustainable #solar parks are helping to save the declining bee population. Bio-diverse spaces are being created around solar energy fields, with acres of wildflower meadows that are fenced in to protect the sensitive habitat. The clean energy generated by the solar field also helps alleviate climate change -- a major threat to the bee population.

Pesticides are probably the #1 cause of the decline of bees, but monocrop farming is also very damaging because it creates vast amounts of land hostile to bees. Any opportunity to diversify land and provide a food source for bees helps. I'm in the process of adding more bee friendly plants on my property to make it Bio-diverse. The more we do this the better.

Is marine energy our path to a greener future?

Ocean energy could a predictable and abundant source of energy. It has the potential to supply 10% of the world’s electricity needs. As the UK possesses 50% of Europe’s wave energy potential, Britain is a clear leader in this sector!

However, marine energy is dependent on government funding. Limited budgets mean that the ocean’s resources remain largely untapped. Could private investment be the answer to this dilemma? 

Let us know your thoughts:

I have no inherent objection to wave or tidal power but I do worry about the environmental impact.  It is hard to imagine how one could build a tidal or wave power plant on a useful scale that wouldn't have a substantial impact on the sea life in the area.

Costco is selling LED can light retrofit kits with a rebate from the local utility (in some locations).  The total cost after rebate (given at checkout, no forms to fill out) for a very bright (1200 lumens) very high color rendering (over 90) kit is about $11.  I bought a bunch of them to install in place of some screw in LED bulbs with much lower color rendering (though I did like the higher color temperature of the old LEDs) that cost over $30 each.  I am using the old LEDs for outdoor lighting where the color rendering is less important to me.
