EIA: Renewables account for almost 10 percent of US energy in 2014
Not since the time when the majority of Americans burnt wood for heat— about the 1930s, most recently— have renewable sources of energy been as heavily relied on as they were in 2014.
That comparison and the data it's based on come from the U.S. Energy Information Administration (EIA), which said on May 28 that renewable energy accounted for 9.8 percent of the United States' total energy consumption in 2014. This is roughly in-line with a 5 percent year over year increase in renewables’ total market share that has been continuing since 2001.
This increase was in due— although they did have help from smaller, less utilized renewables— from solar, wind and biofuels, which have been the primary areas for investment within the sector.
“Wind energy grew from 70 trillion (British thermal units) Btu in 2001 to more than 1,700 trillion Btu in 2014,” the EIA said. “During the same period, solar energy (solar thermal and photovoltaic) grew from 64 trillion Btu to 427 trillion Btu, and the use of biomass for the production of biofuels grew from 253 trillion Btu to 2,068 trillion Btu.
They added, “Hydroelectricity was the largest source of renewable energy in 2014, but hydro consumption has decreased from higher levels in the mid-to-late 1990s. Wood remained the second-largest renewable energy source, with recent growth driven in part by demand for wood pellets.”

Trafigura and Yara International explore clean ammonia usage
Reducing shipping emissions is a vital component of the fight against global climate change, yet Greenhouse Gas emissions from the global maritime sector are increasing - and at odds with the IMO's strategy to cut absolute emissions by at least 50% by 2050.
How more than 70,000 ships can decrease their reliance on carbon-based sources is one of transport's most pressing decarbonisation challenges.
Yara and Trafigura intend to collaborate on initiatives that will establish themselves in the clean ammonia value chain. Under the MoU announced today, Trafigura and Yara intend to work together in the following areas:
- The supply of clean ammonia by Yara to Trafigura Group companies
- Exploration of joint R&D initiatives for clean ammonia application as a marine fuel
- Development of new clean ammonia assets including marine fuel infrastructure and market opportunities
Magnus Krogh Ankarstrand, President of Yara Clean Ammonia, said the agreement is a good example of cross-industry collaboration to develop and promote zero-emission fuel in the form of clean ammonia for the shipping industry. "Building clean ammonia value chains is critical to facilitate the transition to zero emission fuels by enabling the hydrogen economy – not least within trade and distribution where both Yara and Trafigura have leading capabilities. Demand and supply of clean ammonia need to be developed in tandem," he said.
There is a growing consensus that hydrogen-based fuels will ultimately be the shipping fuels of the future, but clear and comprehensive regulation is essential, according to Jose Maria Larocca, Executive Director and Co-Head of Oil Trading for Trafigura.
Ammonia has a number of properties that require "further investigation," according to Wartsila. "It ignites and burns poorly compared to other fuels and is toxic and corrosive, making safe handling and storage important. Burning ammonia could also lead to higher NOx emissions unless controlled either by aftertreatment or by optimising the combustion process," it notes.
Trafigura has co-sponsored the R&D of MAN Energy Solutions’ ammonia-fuelled engine for maritime vessels, has performed in-depth studies of transport fuels with reduced greenhouse gas emissions, and has published a white paper on the need for a global carbon levy for shipping fuels to be introduced by International Maritime Organization.
Oslo-based Yara produces roughly 8.5 million tonnes of ammonia annually and employs a fleet of 11 ammonia carriers, including 5 fully owned ships, and owns 18 marine ammonia terminals with 580 kt of storage capacity – enabling it to produce and deliver ammonia across the globe.
It recently established a new clean ammonia unit to capture growth opportunities in emission-free fuel for shipping and power, carbon-free fertilizer and ammonia for industrial applications.
