That's not my advice. My advice, which I spelled out, is invest in oil companies because they actually make money now and are low risk, relatively high return stocks compared to extremely volatile renewable companies which are more of a gamble than an investment. Then, when renewables become more of a sure thing and aren't propped up by regulatory help and subsidies, then move into that space. It's pretty simple, but if you're absolutely set on misinterpreting everything I say I guess it can become difficult.

Companies that are better positioned than who? In what field? Are you talking solar vs oil? Ok - let's say companies in oil and gas that are better positioned than First Solar.

Exxon, Shell, BP, Total, and Chevron. Most minimajors, like Apache, Anadarko, Pioneer, etc. are also better positioned. All of those companies have pretty large cash reserves, strong financing, and a deep asset base that can be profitable even in low oil price environments. Combine all of that with an oil price that is recovering and long term will continue to recover to levels that are even more profitable - probably in the 60-80 range longer term (long explanation here but basically the supply glut will balance due to reduced capex from larger companies and state run governments and thus reduced production combined with the temporary stoppage of shale plays that are largely irrelevant in the medium term combined with increasing demand from India and China). Data on all of this can be found with the IEA for demand, and then with each individual company's capex numbers - alternatively there are groups that have aggregated these numbers - something like $400 Billion in capex has been cut, and the resulting production loss is pretty well documented. You can search for that yourself.

As far as a group like First Solar, they're heavily reliant on actual cash subsidies from the government - you can find the information widely on the internet, but essentially the gist of it is that renewable energy is the most heavily subsidized energy per unit of energy of any type of energy. If the government decided to reduce subsidies or cut all subsidies, renewable energy would be most affected. First Solar is the strongest of the solar companies, but they're in a market similar to oil - they're selling a commodity and really can only compete on price. That means that if someone comes up with a different method of manufacturing PV cells, or one of their components become more expensive, their competitive advantage disappears. In a developed industry, this isn't as much of a worry. But when your only advantage is price, and the price is of renewable energy is subsidized by the government, and your entire industry is subject to a challenging regulatory environment that could entirely change your business at the drop of a hat (see: energy grids and all the issues surrounding charging solar customers more in order to have them pay their fair share of infrastructure costs or disallowing the selling of energy back onto the grid) and that all could spell reduced demand for solar. Combine ALL of that with the time-proven fact that development of a technology is not exponential forever, and eventually solar growth will drop off somewhat and will not gain in efficiency as fast as it currently does. That could have an effect on the profitability of solar companies and investors outlook on those companies. Solar has widely crashed from its highs in 2008 (FSLR was at ~300/share then), and there are starting to be more realistic expectations for the sector as a whole. Solar is a gamble with a lot of variables. Oil is still a bet, but a much more sure one. It's like betting on the 4-1 horse vs the 25-1 horse.
