Dreamester, I'm afraid you're mistaken.
There is absolutely no requirement for a placement in industry to get an MEng. How do I know? I have one, and did not do a year in industry.
With regards to EE or EEE, It is down to you. I would argue that EEE is better to get into renewables, as the Electrical side is more relevant. That said, I work for a High-Voltage power systems company and did EE. I work alongside physics/ mechanical engineering, civil engineering and nuclear graduates, all working on the same sorts of things - and our degree discipline isn't particularly relevant.
The point of engineering is that it is highly transferable. Indeed, it is extremely likely that all engineering university courses will have the same 1st and 2nd year layout, with just a few optional modules which are stream-specific (electronics/electrical/aerospace/civil etc.)
With regards to which one you should do - BEng/MEng/MSc, that is down to you. Enrolling on an MEng course and then transferring to a BEng is easier than the other way around. BEng + MSc, whilst not equivalent academically to an undergraduate MEng, is no different when you're applying for a job - they both meet the masters level academic requirement required for professional engineering chartership.
A number of high profile engineering firms will generally only take on Masters students (MEng or MSc) because of this. This is not always the case, and with the much higher fees, it is entirely possible that they may start taking BEng graduates. You often have the opportunity at a later date to do an industry funded (free for you) MSc with most large companies. I myself am doing a 2nd MSc to compliment my MEng.
Work placements are a very good idea, either throughout the summer, or as a year in industry. If your chosen university doesn't offer a sandwich year, you can always apply for summer placements, and that is what I did. It's a great way to trial real engineering, and if you're lucky you can get a job offer based on your summer/ year work. You'll also most likely be paid, which is very useful for your student union beer tokens.
Also, as an aside, ensure you look at the IET (Institute of Engineering and Technology) scholarship schemes such as the power academy. They're open to students enrolling at specific universities and offer work placements and money towards your fees, with NO tie ins afterwards. 60 places per year, guaranteed work placements, potentially 20 grands worth of money over 4 years, with no tie ins at the end. What is not to like?
