With supply exceeding demand, producing the silicon panels for photovoltaic (PV) power generation has been an intensely competitive business for several years. There are however reports that a turnaround is underway. Solar industry observers like Greentech Media (GTM) state that with capacity growing only slowly, manufacturers are beginning to see signs of better margins ahead.
For most of us, the air we breathe is cleaner now than it was a decade ago. That’s good news, but it does depend on where you live. The American Lung Association’s (ALA) 2015 “State of the Air” report says, “Nearly 138.5 million people—almost 44 percent of the nation—live where pollution levels are too often dangerous to breathe.” The situation is especially bad in the western USA, with many urban areas in California suffering high levels of air pollution.
Despite all the low energy lightbulbs and high efficiency appliances, demand for electricity is projected to increase over the next 25 years. More air conditioners will be installed in southern states to meet the needs of the growing population and more power will be needed for factories, shops and warehouses. The US Energy Information Administration (EIA) predicts that between 2014 and 2040 residential electricity usage will grow 21%, commercial use by 27% and industrial use by 30%.
We’ve all been through an automatic car wash at some point in our lives. We sit patiently inside the car while it sprays soap, scrubs, blasts and rinses the car right before our eyes. But have you ever take a moment to think about how the system works and how large the car wash industry actually is?
There are more than 150,000 retail car wash locations around the world, according to the International Carwash Association. The US car wash industry includes about 14,000 companies with a combined annual revenue of about $6 billion. There are some pressing issues confronting the global car wash industry including environmental concerns, water and gas prices. The profitability of car wash locations depends heavily on favorable location and efficient operation.
Pumps come in many shapes and sizes and have endless applications in manufacturing, energy, food processing and mineral mining. High flow pumps can take on some of the world’s toughest jobs. For example, barrel pumps transport crude oil at 700 degrees Celsius, centrifugal pumps can build islands and beaches and larger centrifugal pumps can move fluids at 200,000 gallons per minute. ChemTec’s specialty is in low flow valves and monitors, and for pumps, this means applications in sampling, hydraulic and cooling systems, applications we might encounter every day.
