The military has initiated a new covert operation—the greenification of their forces through new and profitable sustainable measures. In fact, $3.6 billion dollars of the $787 billion dollar stimulus fund went towards greening the military. Though it sounds entirely improbable, the patriotic image of gas-guzzling hummers stampeding over the horizon may have been replaced by an eco-conscious military, trading in petroleum for massive billion dollar solar arrays.

While the idea of a tree-hugging military sounds ideally picturesque, the eco measures taken by the armed forces mostly have to do with cost savings. Simply put, green energy sources -- while they maintain efficiency -- are much more affordable than traditional energy sources. Since the military is one of our nation’s largest energy consumption entities, these savings radically compound, lowering our nation’s overall energy expenditure in drastic ways.

THE AIRFORCE

Take for instance the green flight of the Air Force, who leads the nation as one of the top green power purchasers. In fact, the Environmental Protection Agency (EPA) ranked the Air Force as the 16th on their Top 25 list of Green Power Partners, beating out big corporations like Google, and even the EPA themselves. Currently, six percent of the Air Force’s facility energy comes from green power sources, which is well above the federally mandated goal of five percent. What is more refreshing is that the Air Force is planning on further improving their sustainable measures by implementing green energy projects utilizing energy in the form of solar photovoltaic, solar thermal, geothermal heat pumps, wind, daylighting, landfill gas and waste energy.

GREEN BASES

One of the most significant sustainable measures the military has developed is their retrofitting of naval bases with green technology. Most impressive was the military’s greening of the world’s most expensive prison – the Guantanamo Bay Naval Base in Cuba.

In an effort to save money, and decrease dependencies, the base -- which receives all of its supplies from ship or aircraft due to disassociation with Cuba -- is streamlining its domestic energy use on the base to conserve energy expenditures. Simple switches, including the changing of petroleum-fueled patrol cars to bikes and solar-powered lighting saves the military approximately $100,000 dollars a day in fossil fuel dependency.

SOLAR TECH

The military’s big buck budget has enabled them to invest heavily in solar technologies, which promise a huge fiscal reward to bottom-line expenditures, while having no detrimental environmental impact. Over the 2012 year, the military will invest approximately one billion dollars into solar outfitting military housing communities. In addition, big solar-outfitting projects were established at military bases in San Diego, Pearl Harbor, Buckley Air Force Base in Aurora, Colorado, the Marine Corps Air Ground Combat Center in Twenty Nine Palms, California and a naval base in Guam.

This massive flurry of green initiatives and innovations in the military are exciting and necessary on many fronts. Firstly, they utilize the purchasing power of the military to provide much needed capital to green energy companies, which positions them to compete against established fossil fuel titans. Also, as a huge consumption force in America, the military’s sustainable initiatives make a huge impact in national energy use, replacing hazardous effects with clean resources.

All in all, the military’s green movement spends our tax-paying capital in a way that is beneficial to initiatives beyond the armed forces -- they help create a country fortified by sustainable energies that nourish our relationship with earth, instead of destroying it.

Major move forward for UK’s nascent marine energy sector

The UK’s nascent marine energy sector starts exporting electricity to the grid as the most powerful tidal turbine in the world begins to generate power

Although the industry is small and the technologies are limited, marine-based energy systems look to be taking off as “the world’s most powerful tidal turbine” begins grid-connected power generation at the European Marine Energy Centre

At around 74 metres long, the turbine single-handedly holds the potential to supply the annual electricity demand to approximately 2,000 homes within the UK and offset 2,200 tonnes of CO2 per year.

Orbital Marine Power, a privately held Scottish-based company, announced the turbine is set to operate for around 15 years in the waters surrounding Orkney, Scotland, where the 2-megawatt O2 turbine weighing around 680 metric tons will be linked to a local on-land electricity network via a subsea cable. 

How optimistic is the outlook for the UK’s turbine bid?

Described as a “major milestone for O2” by CEO of Orbital Marine Power Andrew Scott, the turbine will also supply additional power to generate ‘green hydrogen’ through the use of a land-based electrolyser in the hopes it will demonstrate the “decarbonisation of wider energy requirements.” 

“Our vision is that this project is the trigger to the harnessing of tidal stream resources around the world to play a role in tackling climate change whilst creating a new, low-carbon industrial sector,” says Scott in a statement. 

The Scottish Government has awarded £3.4 million through the Saltire Tidal Energy Challenge Fund to support the project’s construction, while public lenders also contributed to the financial requirements of the tidal turbine through the ethical investment platform Abundance Investment.

“The deployment of Orbital Marine Power’s O2, the world’s most powerful tidal turbine, is a proud moment for Scotland and a significant milestone in our journey to net zero,” says Michael Matheson, the Cabinet Secretary for Net-Zero, Energy and Transport for the Scottish Government. 

“With our abundant natural resources, expertise and ambition, Scotland is ideally placed to harness the enormous global market for marine energy whilst helping deliver a net-zero economy.

“That’s why the Scottish Government has consistently supported the marine energy sector for over 10 years.”

However, Orbital Marine CEO Scott believes there’s potential to commercialise the technology being used in the project with the prospect of working towards more efficient and advanced marine energy projects in the future. 

We believe pioneering our vision in the UK can deliver on a broad spectrum of political initiatives across net-zero, levelling up and building back better at the same time as demonstrating global leadership in the area of low carbon innovation that is essential to creating a more sustainable future for the generations to come.” 

The UK’s growing marine energy endeavours

This latest tidal turbine project isn’t a first for marine energy in the UK. The Port of London Authority permitted the River Thames to become a temporary home for trials into tidal energy technology and, more recently, a research project spanning the course of a year is set to focus on the potential tidal, wave, and floating wind technology holds for the future efficiency of renewable energy. The research is due to take place off of the Southwest coast of England on the Isles of Scilly
