Renewable, local power options expand

by Triplepundit  (May 15, 2015)

It makes no economic sense to run more than one set of wires from electric power generators to homes and businesses. That’s why consumers haven’t had a choice about the source of their electric power – whether it be an investor-owned utility (IOU), municipal utility or electric cooperative. Enabling consumers to choose between ...

2014 JRC Ocean Energy Status Report

by European Commission, Joint Research Centre  (May 11, 2015)

Abstract Oceans and seas have the potential to play a significant role in providing clean energy. Different technologies are currently being developed to ensure a long term contribution of ocean energy to the future energy system. Among the different ocean energy technologies, tidal and wave conversion systems are expected to contribute the most ...

DESMI Lifts Green Ship Business Case

by DESMI A/S  (Apr. 30, 2015)

New rules call for fresh approach It’s hardly news that the shipping industry is mobilising to meet the demands of wave after wave of new environmental regulations. From the IMO’s ballast water management legislation to EEDI (the Energy Efficiency Design Index for new ships) and SEEMP (Ship Energy Efficiency Management Plan), ...

Study on hydrodynamics and heat transfer of solitary wave on film flow with CFD method

by Inderscience Publishers  (Mar. 6, 2015)

In this paper, a capacitance probe and high speed camera are adopted to study the solitary wave of falling film on large flat plate experimentally. Two types of solitary wave are studied with a Computational Fluid Dynamic (CFD) method based on the measuring data. The water–air shear stress on the interface of the solitary wave is modelled in the ...

Earthy, solaris and atmospheric energy sources

by Inderscience Publishers  (Feb. 19, 2015)

Earth, sun and atmosphere are the ultimate energy resources. In addition to fossil fuels, earth radiates over 45 TW geothermal energy. Sun radiates about 89 PW energy to earth's surface. Lunar gravity supplies over 100 GW tidal ocean energy. Accessible energy from geothermal, solar, tides, waves and winds is far more than our current 17 TW energy ...

National Grid Alert Triggers Wave of Enquiries for Renewables Sector

UrbanWind today reported a sharp increase in companies enquiring about on-site power generation, following National Grid’s warning yesterday.   It said growing numbers of British businesses were now looking to move towards ‘energy independence’ to protect themselves from the rising threat of future brownouts. ...

Energy and war – intertwined then and now

by Energy Institute (EI)  (Sep. 10, 2014)

Given that it is the 100th anniversary of the start of the First World War, there has been a lot of focus on 1914. Whilst our own EI century seems such a small event in comparison to the Great War, it does provide an interesting context. The August 1914 issue of Petroleum Review said “The review has never taken sides politically…yet ...

Marine crude oil transport – global voyage losses

by Energy Institute (EI)  (Sep. 1, 2014)

Paul Harrison, Consultant to the HMC-4A Marine Oil Transportation Database Committee, presents latest findings from analysis of the 2013 data on marine crude oil transport. The Energy Institute (EI) HMC- 4A Marine Oil Transportation Database Committee has been collecting and analysing worldwide oil shipping data for over 20 years and meets twice ...

Power control strategy for grid connected permanent magnet synchronous generator of a distributed generation unit

by Inderscience Publishers  (Jul. 7, 2014)

This paper describes the studies on the operation and control of a variable speed wave energy conversion system. The wave energy conversion system considered is oscillating–water–column (OWC) based Wells turbine driven permanent magnet synchronous generator connected to the grid by means of fully controlled frequency converter. In such systems ...
