absolutely wrong ,haha.
the biggest consumers of coal are handruds of thermal power plants.and the biggest consumers of electricity are metallurgy and mechanical industries.don't forget we produce about 50% steel and electrolytic aluminum of the world.and we are the biggest ship and construction machinery manufacturer and consumer.and cars ,too.
what you mentioned such as electronics industry does not consume much electricity /coal.
Electronics industry's "processing trade" only inflates the export / import numbers. It doesn't contribute much to the trade surplus.
Let's see Foxconn:
Revenues: $ 120 Billion
Foxconn imports $ 110 Billion; Foxconn exports $ 120 Billion
Now, do you see how the Trillion dollar exports / imports are build up??
(and do you see how big is Foxconn's imports / exports as a percent of China's imports / exports !)
Next: Foxconn employees: 1.23 million
Even if each one of them were to earn $ 5,000 (which is quite high a figure for chinese labour), Foxconn would pay total $ 6.2 Billion.
Add Foxconn's profit = $ 2.7 Billion
Add the two, 6.2 + 2.7 = 9 Billion is the total contribution of Foxconn to china's export surplus.
In summary, the bulk of import / export comes from Foxconn type "processing trade" companies but their contribution to trade surplus is relatively less.

Where is the trade surplus coming from?? --- because chinese don't consume 50% of the world's coal. Their living standards don't show that this 20% of the world's population is enjoying 50% of the coal. (True, 25% of the world's coal, perhaps, is indeed consumed by this 20% of the world's population).
What happends to the remaining 25% of the worlds' coal .... it goes into building the goods consumed outside china ... in Europe, in USA.. and well, maybe, in India too.
Well, if you sell $ 175 billion worth of coal for beneficial use of rest of the world .. you'd want to see that amount in the trade surplus.
