As usual, it always comes down to cost for the end-user. You're talking bout cost and energy savings, and a significant enough portion of the power produced by Eskom is used by ppl with illegal connections, subsidized by ppl who pay for electricity.
Along with this new energy saving legislation, there's also plans for an 18% increase in electricity costs.
Ppl in the lower income brackets don't buy energy saver bulbs, cos they just can't afford and it. The only ppl conscious about saving electricity are the ppl who pay for it.
You'd be surprised how many shacks have got fridges, stoves and electric heaters.
So I believe my previous statement carries some relevance to this thread.
At the time you first mentioned illegal connections, your comment had no relevance - the thread is about renewable energy - it makes no difference who uses that energy or if they pay for it or not - the source of the energy is the subject at hand.
Since then, the thread has moved more towards energy saving - nonetheless, solar panels are an alternate, greener source. Cost savings are mentioned as a means to justify the expense.
Again, illegal connections are not relevant.
