Light Emitting Diodes, more commonly known as LEDs, are the most energy efficient lighting available with the exception of natural sunlight itself.  While homes and businesses improve their energy efficiency to lower electricity bills, lighting is a chief concern.  Most people are aware of the energy sucking drawbacks of traditional incandescent light bulbs, and tend to turn to Compact Fluorescent Lights (CFLs) instead of LEDs primarily for price point.  CFLs are more on-par with the initial costs of incandescent bulbs than their LED counterparts, but contain harmful compounds such as mercury, which makes discarding the bulbs a potential danger.  Now, a partnership between Lighting Science Group and Dixon Technologies may see the price of LEDs finally coming down.

Lighting Science Group is one of the world’s premier LED lighting solutions companies and Dixon Technologies is an Indian-based manufacturer of electronics technology.  The two partners have recently unveiled their first joint product, an omnidirectional 60-watt equivalent A19 LED bulb that will sell for less than $15. Lighting Science Group will introduce the bulb to India’s lighting market late this year, with an international release expected in early 2012. 

"With 800 million incandescent light bulbs and 300 million CFLs sold in India each year, the market is ripe for these highly efficient, long lasting and nontoxic products," says Atul Lall, deputy managing director of Dixon Technologies. "The economic and environmental implications of this partnership are significant: old-style light bulbs use 60 billion units of electricity each year, seven percent of India's total, and our Lighting Science Group Definity® lamps could save over 70 percent of that, equivalent to 32 coal fired plants with 500MW capacity."

The Lighting Science Definity® bulb screws in just like its incandescent predecessor, but uses 85 percent less electricity.  When compared to CFLs, the bulb saves 35 percent more energy, and contains no toxic mercury.  While the initial cost of just under $15 per bulb may still terrify the bargain shopper, the average payback time in energy savings is only eight months, and the bulb has a lifespan of about eight years.  The full line of the new Definity® products will include street lights, outdoor and industrial lighting fixtures and replacement bulbs.

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
