Following 2009, auto sales in the United States and Europe are expected to begin a slow recovery. The situation is not expected to improve in the near future, with U.S. and Western European sales not expected to recover to 2007 levels for five or six years. This is a grim picture indeed, even for our industry, but for sure there will be a revolution in the power technology used here. One of the harshest criticisms of the auto industry has been that it kept on doing what it was good at; producing We find ourselves now right at the the same old stuff without embracing the start of the forthcoming calendar year, new ideas and technologies available. although I’m still wondering what Let’s hope things move forward here happened to the year – it went so fast. faster than predicted. I’m not going to devote valuable space and bore everyone rigid in the process, Aside from the economic reports of with a detailed look back but would doom and gloom, the fact is we have an instead rather look forward. Even though industry poised to achieve even greater we are facing, or indeed in, difficult things than ever before, and the need times, we have a very solid industry has never been so desperate. overall, and power has never had such a pivotal role to play in the well-being National’s boss, Brian Halla talks of our engineers, our industry and our about the ‘megatrends’ in the industry environment. reported in the ‘On-the-Road’ section of the magazine (also see my web This issue is themed on renewable exclusive extended electronica report by energy. For renewable energy I believe going to our home page and simply click we can read renewable opportunities, on the electronica logo), representing businesses, as well as environmental his vision for the opportunities in front of well-being. Sounds a bit corny? us rather than the ‘oh’s and woes’ in the Just consider the amount of good current thinking of some other leaders. engineering and management that This is just the kind of inspiration and supports this potentially vast industry.
