India's solar energy installed capacity has swelled from practically nothing to more than 2 GW in the three years since the creation of the Jawaharlal Nehru National Solar Mission Phase 1 (JNNSM). Impressively, costs have come down rapidly (to roughly $0.12/kWh for solar PV, and $0.21/kWh for CSP) to be competitive with grid-connected solar PV in many other regions.

It’s easy to get caught up in the holiday bustle: shopping, decorating, parties, and preparation. Our to-do lists can seem endless, but we carry on because it is that special time of year, a season of giving.

Alaska’s 720,000 people live in over 200 “energy islands” with no electricity grid connection to each other nor to North America. Smaller communities have no road connection to each other, the rest of Alaska, or the continent. Most energy is imported: diesel for electricity generation and heat; gasoline for transportation. All Alaskans might obtain an annually-firm supply of most of their energy, for all purposes, by converting Alaska’s diverse, stranded, renewable energy (RE) resources to liquid anhydrous ammonia (NH3) fuel, transporting and storing it at low cost in common steel propane tanks, recovering the RE via stationary combined-heat-and-power (CHP) plants, in internal combustion engine (ICE) and combustion turbine (CT) gensets, and via fuel cells, and as transportation fuel. Alaskans could achieve a significant degree of community energy independence, and perhaps export their abundant, stranded renewables as “green” liquid NH3 fuel. Solid state ammonia synthesis (SSAS) appears promising.

A Louisiana lumber town has become the crossroads for an unusual buyer and seller in the U.S. municipal market: private-equity firm KKR & Co. and the world’s biggest manufacturer of wood pellets.

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.

Executives from 13 major U.S. corporations are announcing at least $140 billion in new investments to decrease their carbon footprints as part of a White House initiative to recruit private commitments ahead of a United Nations climate-change summit later this year in Paris.

Companies including Apple Inc., Berkshire Hathaway Energy Co., and Goldman Sachs Group Inc. will join Secretary of State John Kerry and top administration officials at the White House for the announcement. In addition to pledges to cut emissions, provide financing to environmentally-focused companies, and reduce water consumption, the companies have said they will procure at least 1,600 MW of new, renewable energy. The White House said in a statement that it expects to announce a second round of similar pledges later this fall from additional companies.

The commitments are being announced as President Barack Obama is looking to build momentum toward a legacy-defining global climate accord in Paris. In addition to company-specific commitments, the corporate leaders on Monday will signal their support for a strong climate agreement out of the United Nations talks. They administration is using the pledges to set an example for companies to find ways to eliminate their carbon emissions.

Climate Talks

“As the world looks toward global climate negotiations in Paris this December, American leadership at all levels will be essential,” the White House said in a fact sheet detailing the announcement.

The administration’s actions are pushing the issue into the 2016 presidential debate. Hillary Clinton, the front-runner for the Democratic nomination, released an energy strategy saying she would both defend and go beyond Obama’s efforts. Republican candidates have criticized the administration’s initiatives as costly to the economy and unnecessary.

Among the pledges, aluminum manufacturer Alcoa Inc. has agreed to reduce emissions by 50 percent from its 2005 levels, while agricultural giant Cargill Inc. says 18 percent of its total energy use will come from renewable sources.

Coca-Cola Co. said it would drive down the carbon footprint of its beverage production by 25 percent over the next five years, while Google says it plans to triple its purchases of renewable energy over the next decade.

Other participating firms include Wal-Mart, United Parcel Service Inc., PepsiCo Inc., Microsoft Corp., General Motors Inc.

The corporate commitments won’t be the administration’s only major climate announcement in the next few weeks. The Environmental Protection Agency is set to present final regulations that aim to reduce carbon emissions from power plants by 30 percent from 2005 levels by 2030 later this week.

While visiting Kenya over the weekend, Obama repeatedly praised the country for its efforts to address climate change, saying its efforts tor educe emissions “has put it in the position of being a leader on the continent.” And next month, the president will travel to Alaska for an international summit on Arctic climate issues.
