Berkeley Lab: It Takes 70 Billion Kilowatt Hours A Year To Run The Internet Christopher Helman; Forbes; 28 Jun 2016
- America’s myriad server farms and data centers operate 100 million drives that hold 350 million terabytes of data — everything from your decade-old emails to lolcat videos and the collected offerings of Netflix. A new report from the Department of Energy’s Lawrence Berkeley National Laboratory figures that those data centers use an enormous amount of energy — some 70 billion kilowatt hours per year. That amounts to 1.8% of total American electricity consumption. At an average cost of 10 cents per kwh, the annual cost of all that juice is on the order of $7 billion.
Energy Efficiency: Shaping the United States Energy System James Sweeney ( director of the Precourt Energy Efficiency Center, Stanford University); 30 Nov 2015 Video of Energy Seminar
- Ever since the oil embargo of 1973-74, private and public U.S. energy discussions have centered on energy impacts to three complex and crucial systems: the economy, the environment, and national and international security. Policy debates have deadlocked trying to balance tradeoffs among these essential systems. Energy efficiency, on the other hand, is good for the economy and the environment, while enhancing security. It should be no surprise that since the oil embargo of 1973-74, individuals, corporations, and other organizations have found ways of economically reducing energy use. Nor should it be a surprise that federal, state, and local governments have enacted laws and regulations to promote energy efficiency.
- However, many will find the remarkably large energy efficiency results surprising. Since the energy crisis of 1973-74, U.S. energy efficiency has done more to curb greenhouse gas emissions and to reduce net energy imports than have increases in domestic production of oil, gas, coal, geothermal energy, nuclear power, solar power, wind power, and biofuels – all taken together

grids / integration
Electricity Transmission Systems World Nuclear Association; Nov 2015
- National and regional grid systems connecting generators with wholesale customers are generally just as important as electrical power generation.
- Investment in these is often on a similar scale to generation capacity.
- New technology is enabling transmission at high voltages over long distances without great losses.
- Transmission system operators have responsibility for the quality of power supply.
- Countries with well-developed electricity infrastructure have established grids run by transmission system operators (TSO) to convey power to distribution systems where it is needed. Where generating plants can be located close to load centres, these are less important than where the plants are remote, as with many hydro-electric plants and wind farms. Lower voltage can be used. At higher voltages, eg 500kV and above, transmission losses over hundreds of kilometres are much reduced. At ultra-high voltages (UHV) eg 1000 kV AC or 800 kV DC, losses are further reduced (eg to 5% over 1000 km) but capital requirements are greater. In Germany consideration is being given to converting some existing AC lines to DC to increase their capacity. In the USA it is estimated that transmission losses amount to about 6%, or 250 TWh per year, worth some $20 billion. In India transmission losses in 2011 were 222 TWh (21%).
Smart energy could save £8bn a year, say advisers Roger Harrabin; BBC; 4 Mar 2016
- Ofgem is challenging local electricity grid owners to follow Western Power Distribution’s lead by squeezing more capacity out of their grids to connect renewables.
- There is huge growth in renewable generation in Great Britain. By December 2015 8.6GW of solar capacity had been installed 15 years ahead of forecasts.* Official projections made in 2012 suggested that around 6.5GW of solar panel capacity would be connected by 2030.
- In some regions including the South West, there is little spare network capacity meaning costs and timescales for connection can be extremely high. So Ofgem is calling on electricity distribution network operators (DNOs) to speed up connections, firstly by finding new ways to link more generators to the existing network.

Global Supergrid Funding To Reach $10.2 Billion By 2025 Joshua S Hill ; Clean Technica; 7 Oct 2016
- Navigant Research published its new report this week, Supergrids, analyzing the potential market for supergrids — large-scale, high-voltage transmission systems spanning countries, continents, and possibly even the globe one day. Such grids would allow multiple electricity generation technologies to input into one grid, creating a more reliable grid whilst simultaneously allowing the bulk integration of renewable energy.
- For example, a supergrid spanning the Middle East and North Africa, with links into Europe, would be able to utilize the plentiful solar resources of the MENA region and the North European wind energy resources, and mitigate variability with the sheer availability of renewable energy resources across such a large swath of the area, including the varying climate conditions.
UK - Norway interconnect
National Grid plans world's longest underwater power cable between Britain and Norway Rowena Mason; Telegraph; 6 Oct 2009
- National Grid, the UK's network operator, yesterday made an agreement with its Norwegian equivalent, Statnett, to draw up proposals for a link-up that is likely to cost around £1bn.
- Part of the plan involves locating wind turbines along the route to provide top-up power and connecting to oil and gas platforms to provide electricity.
- The two countries are a good energy match, because Norway's gets most of its electricity from hydropower stations and the UK is planning to build more wind farms.
- A cable link-up could help solve the problem of wind power intermittency, where Norwegian hydropower could act as back-up for the UK in return for electricity on windy days.
Ofgem approves a 354-mile power cable from UK to Norway Jillian Ambrose; Telegraph; 21 JUN 2016
- consortium that plans to build a 345-mile power cable to bring renewable hydro power into Britain.
- NorthConnect aims to transport Norway’s abundant hydro-power reserves in the south west of the country through a high voltage 1.4GW subsea cable to a substation at Peterhead in Aberdeenshire. Under current plans the project will begin powering homes by 2022.
- There are currently four interconnectors to mainland UK, from France, the Netherlands, Ireland and Northern Ireland, with a combined capacity of 4GW. But ministers have said they would support a further 9GW of new interconnectors to help to improve security of supply by giving the UK access to power generated elsewhere.
World's longest subsea power link to generate at least £1.3bn income for National Grid Emily Gosden; Telegraph; 18 OCT 2016
- National Grid is to be guaranteed a minimum of £1.3bn income for building the world's longest subsea power cable to import electricity from Norway. Energy regulator Ofgem on Tuesday announced plans for consumers to guarantee the utility giant at least £53m annual revenues for 25 years in return for its 50pc investment in the £1.4bn North Sea Link interconnector. The 450-mile cable from Blyth in Northumberland to Kvilldal in Norway is due to be built by 2021 and will be the first electricity link between the two countries. It will be able to import or export up to 1.4 gigawatts (GW) of electricity - enough to power about three quarters of a million UK homes.
power line bird mortalities
Refining Estimates of Bird Collision and Electrocution Mortality at Power Lines in the United States Scott R. Loss,1,*¤ Tom Will,2 and Peter P. Marra1; PLOS One; 3 Jul 2014
- Collisions and electrocutions at power lines are thought to kill large numbers of birds in the United States annually. However, existing estimates of mortality are either speculative (for electrocution) or based on extrapolation of results from one study to all U.S. power lines (for collision).

Denmark accused of keeping quiet over "environmental disaster" that saw fertiliser and oil pour into the sea during fire Lizzie Dearden; Independent; 28 Feb 2016
- Several thousand tonnes of liquid fertiliser burst out of a silo in Frederica Harbour on 3 March, causing palm oil to leak from a neighbouring vat and catch on fire, starting a huge blaze. But a Danish newspaper has accused local authorities of failing to announce the impact of the accident for several weeks, amid fears that huge amounts of toxic substances flowed into the sea and could kill countless fish.
Long working hours and risk of coronary heart disease and stroke: a systematic review and meta-analysis of published and unpublished data for 603 838 individuals Mika Kivimäki et al; The Lancet; 31 Oct 2015
- Employees who work long hours have a higher risk of stroke than those working standard hours; the association with coronary heart disease is weaker. These findings suggest that more attention should be paid to the management of vascular risk factors in individuals who work long hours.
Working long hours is linked to a significantly higher risk of stroke PETER DOCKRILL; Science Alert; 21 AUG 2015
- According to researchers in the UK, those who work longer hours during the week significantly increase their chances of having a stroke. In the largest research project of its kind, researchers from University College London reviewed 25 studies involving more than 600,000 men and women from across Europe, the US, and Australia. Looking at the data, they found that those working 55 hours or more per week had a 33 percent greater risk of stroke than those working a more balanced 35–40 hour work week. Working the longer set of hours also brings with it a 13 percent increased risk of developing coronary heart disease.
