The National Renewable Energy Laboratory’s solar cell efficiencies chart depicts confirmed conversion efficiencies for research cells from 1976 to date, for several PV technologies. But as conventional crystalline silicon (c-Si) PV modules approach peak efficiency, with the leap from lab to life—or from demonstration to mass production—occasionally taking over 30 years, the final question is: what is the additional watt class worth?

(Mon, 16 Oct 2017) EIA forecasts that U.S crude oil production will average 9.4 million barrels per day (b/d) in the second half of 2017, 340,000 b/d more than in the first half of 2017. Production in 2018 is expected to average 9.9 million b/d, surpassing the previous high of 9.6 million b/d set in 1970, based on projections in EIA’s <em>Short-Term Energy Outlook</em> (STEO).

Power-to-gas (P2G)—the conversion of electrical power into gaseous energy carriers—is a quickly improving and potentially disruptive energy conversion technology. 

It is not always good to be first. Last June, San Diego Gas & Electric (SDG&E) was the first utility in California to hit its net-metering cap and move to Net Energy Metering 2.0 (NEM 2.0). Now, SDG&E will again be the first utility to start the shift to time-of-use (TOU) period, effective on Dec. 1, 2017.

Europe must prevent using trees and crops as a way to meet renewable-energy requirements or it will risk further increases in food prices, deforestation and land grabs, environmental groups said.

(Fri, 13 Oct 2017) Relative profits for some natural gas- and coal-fired generators in several Midwestern and Mid-Atlantic states may have decreased since 2016 because of higher natural gas and coal prices and lower wholesale electricity prices. A common measure of profitability for power plants within a region is the difference between their input fuel costs, such as the cost of coal or natural gas, and their wholesale power price

Ocean Rig UDW has signed a new drilling contract with Statoil, for a one-well drilling program offshore Tanzania.

Russian gas giant Gazprom Neft says that its Omsk Refinery in Western Siberia has produced its first batch of RMG-80, a marine fuel claimed to be environmentally friendly.

As the Atlantic continues to churn out some of the deadliest storms on record, the repercussions continue to rock the South and southeastern U.S. Whether it is the physical impact of the recent storms on solar projects or the economic impact throughout energy markets, how do these events affect the solar industry, and to what extent?

Nevada-based Ormat Technologies this week said that the second unit of the Sarulla geothermal power plant in North Sumatra has begun commercial operation.
