According to the latest "Energy Infrastructure Update" report from the Federal Energy Regulatory Commission's Office of Energy Projects, solar, biomass, wind, geothermal, and hydropower "units" provided 394 MW — or 100 percent — of all new electrical generation placed in-service in November 2013. There was no new capacity during the month from natural gas, coal, oil, or nuclear power. Renewable energy sources also provided 99 percent of all new electrical generating capacity in October.

Global private capital renewable energy investments are still above $250 billion for 2013. While the final numbers are not in yet, 3rd quarter global renewable energy investments, according to Bloomberg New Energy Finance’s latest data on deals and projects, notes slightly lower global investment than in 2012 due faltering “political will to decarbonise energy mix.” They further note that the third quarter’s decline in investment will push the year’s overall investment in renewable energy and energy-smart technologies down below 2012's $281 billion. But $250+ billion ain’t shabby.

As editors we delight in learning which of the stories that we wrote or commissioned were most popular with our readers. That’s why at the end of each calendar year, we pull reports that tell us which stories we posted got the most shares, the most views, the most comments, etc. We also look at which videos were watched the most. Often, we post articles that we know will be a big hit: like explanations of controversial solar legislation. But other times you surprise us, readers, by taking great interest in articles that we felt were solid but not necessarily ground-breaking.

Here at RenewableEnergyWorld.com, we pride ourselves on our active community of readers who click, share, and comment on the articles that we post every day. While we don’t always agree with their take on the pieces we post, we always value constructive feedback and the high quality discussion that sometimes ensues.

Bio-energy forest plantations will supplement woody biomass from other sources such as logging residues. In the southern U.S., projections are for an increase of up to 25 million “new” tons of woody biomass demand for bioenergy. To supply this woody biomass demand will require purpose grown plantations of various species including pine, eucalypts, sweetgum, hybrid poplar and cottonwood, amongst others. Forest plantation yields can be 8-15 green tons/acre/year on rotations of 5-12 years. Utilization of this renewable and sustainable biomass resource will be as feedstock “designed” for a large number of bio-energy applications.

The United States broke one record after another for extreme weather in 2013. From deadly floods in Colorado to prolonged drought across the Southwest, Americans saw what unchecked climate change can do to our communities. But we also witnessed another kind of powerful force: real and positive climate action.

We here at RenewableEnergyWorld.com value each and every one of our excellent contributors that share their important and thought-provoking insights with our readers. But we have a special affinity for our outstanding blogging community.
