As far as exporting goes, we don't really make much of anything these days
What are you smoking? In 2007, American exports totaled $1.64 trillion. This is a record and represents the largest increase in modern history (11% over 2006).
To put that into perspective, $1.64 trillion in American exports was greater than the entire GDP of any single country beyond the G-7 (US, Japan, Germany, China, UK, France, Italy). American exports were nearly 4 times greater than the whole GDP of Poland.
Many of your other statements are wrong too. Why are you spreading this kind of disinformation on Polish Forums?
The US is currently an excellent place for investment into manufacturing. Land is cheap. Labor is available, cost is reasonable, and labor laws favor the employer. Taxes are low. Infrastructure is superb. Raw materials are readily available. Financing is still available. There is a large domestic market, and plenty of free trade agreements for overseas exports.
Poland was doing very well lately -- roughly 6% GDP growth, and attracted about $15 billion in FDI last year. Mainly manufacturing into one of the dozen or so special economic zones, where employers enjoy 10 years of tax breaks. Work ethic is also good, labor is (was) cheap, and you can export to anywhere in the EU without tariffs. So lots of big companies were making Poland a manufacturing base for the European market, not really worrying about the domestic market - everything was for export. However infrastructure is poor and labor costs are catching up to regular EU standards. It's very difficult sometimes to procure raw materials; sometimes prices can skyrocket for mundane things. It's also difficult to setup a greenfield investment, and nearly impossible if you're a foreign company trying to do it on your own, without the benefit of a Polish partner. The Polish Government has recently issued an adjustment to its growth rate - they now expect 1% instead of 6%.
As far as renewable energy, currently the EU has mandated that 5% of any country's energy must come from renewable sources. This will be 20% by 2020. So yes there is a growing market everywhere in the EU. Poland however generates 99% of its electricity from coal, and is having a tough time complying. The coal union is very strong, and represents several hundred thousand jobs, mainly in Silesia. There's only a few places here suitable for wind farms, there's not a lot of sun year-round for solar, and underground hot springs are not generally hot enough for geothermal energy.
