Making Motors More Energy Efficient

February 17th, 2012

AC Induction Motors motors literally are everywhere! Almost every mechanical movement that you see around you is caused by an AC (alternating current) electric motor.

They are everywhere and used by everyone. However, they have a fundamental flaw – they often waste unnecessary amounts of energy. An incredible 50% of the world’s energy production is consumed by motors!

London Olympics Lack Energy Saving Plan

February 13th, 2012

LOCOG, the London Organising Committee of the Olympic Games currently do not have an energy-saving strategy. They have vowed to make this years games the greenest Olympics and Para-Olympics to date.

The Commission for a Sustainable London (CSL) 2012 have called for these issues to be addressed urgently, as there is a window of opportunity to make for lost time.

Upgrading Buildings to Improve Energy Efficiency Pays

August 20th, 2011

THE U.S. Green Buildings Council (USGBC) claim that investing in building energy efficiency is central to the country reducing its energy consumption by 23 percent by 2020, saving $1.2 trillion – showing it truly does pay to improve energy efficiency.

The conclusion comes from a study sponsored by USGBC on the benefits of green buildings, combined with other non-transportation initiatives. Apart from the substantial monetary savings, environmentally it will also reduce greenhouse gas emissions by 1.1 gigatons annually.

Energy Efficiency Is The Way Ahead

May 20th, 2011

I read a great editorial a while back in Distributed Energy by Elizabeth Cutright.

She highlights how energy efficiency is the way ahead as far as change energy use for environmental, energy security and energy supply reasons.

As she reports – it is what people want to happening compared to new or old forms of power generation. New power stations are needed but the impact of funding into energy efficiency is paramount.

Here is the bulk of the article:

Upgrade to Energy Efficiency

October 25th, 2010

Anissa S. Febrina has written and interesting article in the Jakarta Post about upgrading buildings so they are energy efficient.

The article, most of which appears below, states how often finding the money for the energy monitoring solutions and the load-side products can be a stumbling block, but the article explains that the money saved from reduced energy bills over a fairly short period provides a great return on investment.

What is also of interest is the article does highlight how Indonesia is now realising how important it is to become energy efficient. I know from speaking to people from Indonesia that climate change, energy efficiency and security has not been a concern – hence it is good to see they are sitting up and taking notice.

Will Compact Florescent Lamps and/or Florescent Fixtures Save the Day?

Compact Florescent Lamp

Compact Florescent Lamp

IT is obvious to say the Compact Florescent replacement lamps (CFLs) can save energy and they will pay for themselves many times over by comparison to powering an incandescent bulb.

I personally use them in my home and office.  I am however not convinced that I am doing the right thing for the power system.

Consider an older home (or office); the electrical system (breakers, transformers, etc.) were engineered for mostly “traditional” linear loads.  An example of a linear load is a resistive load as in incandescent lights, AC Motors and electric heaters.

Power the Future

June 12th, 2010

Gribble - the future of power generation?

Alternative energy sources are always being sought, it was not that long ago that solar, wind and heat pump were slightly off the wall alternative energy sources – now they are regarded as perfectly normal and needed.

Recently I was reading and interesting blog that offered some other sources of energy you may not have thought about (positiveenergy) – maybe alternatives that will be become fully accepted in the not to distant future.

Nations and governments may rely of Gribbles to combat concerns over energy security, let alone climate change – Gribble, yes Gribbles, check out what the future energy sources could be:

Uni Flys to Energy Efficiency

June 2nd, 2010

Wright State UniversityIN Dayton, Ohio, U.S.A., the Wright State University, named after the local claimed inventors of powered flight the Wright brothers, have recently been making substantial energy savings.

Public bodies, such as Universities and Hospitals, are heavy users of energy and a few basic measures can save a substantial amount financially and environmentally.

Wright State have their own newspaper “The Guardian” which in part reported the following details:

Top Ten Tips on Energy Efficiency for Businesses

May 28th, 2010

Managementtoday.com recently had a very interesting post regarding UK businesses and the importance of energy saving – most of the points apply to all businesses wherever they are based, although some points do apply only to UK businesses .

By reducing their dependence on energy, businesses can cut costs, improve reputation, and stay one step ahead of environmental compliance.

Managementtoday asked Hugh Jones, director of solutions at the UK’s Carbon Trust, for his top 10 tips:
