The concept of fuel cells as an energy source is credited to a chemist, William Grove. He demonstrated in 1839 that electric current could be produced by an electrochemical reaction between hydrogen and oxygen over a platinum catalyst. Thereafter, many alternate forms of the technology emerged for producing electricity from various materials and catalysts.

The main reason why fuel cell companies have not been profitable is due to startup and operational costs. Although fuel cells provide clean, inexpensive energy, it is much simpler to use coal or natural gas. These industries have been around for a long time, so their processes are now streamlined.  Unless legislative action requires the use of clean energy, the adoption of fuel cells will remain slow.

Fuel cells are attractive for energy production because they provide clean energy, with no harmful byproducts. Although commercial adoption of fuel cells remains slow, it is possible that the technology could become disruptive and make a significant impact on the energy industry. That could happen if environmental pollution due to the burning of fossil fuels becomes a global concern. So far, large countries that account for a great deal of pollution, such and China, have been indifferent about the pollution they cause.

Today’s infographic breaks down the essential facts about energy efficiency. It explains why energy efficiency is so important, and goes into detail about how wasting energy can harm the environment. Then, after convincing you that conserving power is a good idea, it offers a comprehensive guide to help you start saving more energy at home, assessing the efficacy of your appliances, insulation, and of course, your lighting.

I especially like this infographic for the Incandescent/CFL/LED comparison chart at the very bottom. Good stuff!

Prefabs provide on-site, off-site and other hidden advantages. For instance, faster installation at the job site reduces the project duration. Prefabs have the potential of cutting the installation time by almost a half. In addition, the project will require fewer workers in the field resulting in a big reduction in labor costs and improved profitability.

There’s also a significant savings on labor, which can be very expensive and in short supply. The prefabrication process is considered more of a manufacturing function so the contractor is able to achieve success with fewer workers. The workshop can make use of semi-skilled workers and apprentices, unlike a construction site where an electrician is required to perform the installation.

Fewer materials and less activity at a job site mean that the project is completed faster with a reduced opportunity for accidents and delays. In addition, by delivering all the individual components to the workshop for assembly, the level of material handling is narrowed. This equates to an easy-to-manage supply chain. Fewer materials reduce clutter, waste disposal, and the need for extra storage space.

The workshop provides the best environment for producing the assembly fast without the interruptions that might be found at a construction job site. Further, the production of prefabs is not affected as much by delays from other trades, bad weather, and other construction project hold-ups.

Electricians spend less time working at dangerous heights and precarious positions, hence reducing safety risks. Prefabs allow contractors to reduce the need for as many licensed electricians on the job site. This can result in greater productivity and profitability.

Increased competition and high labor costs have caused declining profits for many electrical contractors. However, with the use of prefabs, profitability can be improved by reducing the labor and time spent at the construction site. Additionally, fabricating electrical assemblies in a workshop makes it easier to stay on budget and hit your project timelines.
