Engineers save the world

Through improvements in energy efficiency, global fossil fuel consumption for power generation could be reduced by up to 30 percent.

Global warming is the most significant challenge we face, so we need to act fast. To inhibit the growing energy demand, the International Energy Agency (IEA) has long stressed two factors: the relationship between economic growth and energy consumption growth and the link between the growth of energy consumption and carbon dioxide emissions.

Medicines to break these linkages are available “off the shelf” already. Energy, be it electricity or fuel, must be used smartly. This means energy efficiency. At the same time, existing technologies enable the utilization of renewable energy sources that do not emit any greenhouse gases. Sounds simple, right?

Here, engineers come to the picture whose innovations make sustainable world possible. As part of a healthy market competition engineers will continue to develop higher efficiency motors and more intelligent variable speed drives. The hard engineering work enables our customers to save 490TWh of energy per year with ABB variable speed drives. Savings equivalent to more than six times of the annual electrical energy consumption in Finland. A large number, but even wilder of this makes the fact that almost 70 percent of the world’s motors are still waiting for an energy-efficient solution. There is enough work for engineers, for sure.

The most important spark of my own work is the ethical side. IEA’s World Energy Outlook takes a strong stand on the link between energy efficiency and living standards. Up to 1.3 billion people in the world lives without electricity and 2.6 billion without the possibility of hygienic food preparation. Energy efficiency measures enabling affordable access to electricity and thus giving an uplift to living standards. There certainly is enough work to be done even after my retirement days.

    Ha ha you are talking about your retirement young boy ,I know when you are going to do this
    the time of thinking from all things you know and where you think why is this like this
    you like to look in to it only to know and maybe you will find a solution to a question because
    you have the time to do this .
    For the rest I do agree with the topic but something you don't know we can lower the energy
    consumption from power plants with 50 % now all ready .
    If we take the energy from 1 M3 gas a 65 cents this having the same energy like 10 KWh
    electricity a 20 cents a KWh so 200 cents .
    In terms of efficiency gas can be 80 % and electricity 100 % so in cost electricity will be 160 cents
    to gas , but if we use them electricity is clean and gas is not clean .
    Now I know we can bring down the cost for 10 KWh 160 cents compared to 65 cents 1 M3 gas
    to 35 cents for 10 KWh and 65 cents 1 M3 gas .
    And you will find out this before you are retired .
