Why do plants have so many leaves?

Not all of them do. A few cacti and some succulents are highly modified stems with no leaves at all. The most famous of the leafless plants is Lophophora Williamsii, better known in the USA as Peyote.
A plant that you cannot legally grow in "the Land of the Free".

And why do they use such a tiny
fraction of available solar energy?

Limitation of the chemistry. C4 metabolism is about as good as it gets. Synthetic organic chemists have yet to equal chlorophylls performance and have the whole system remain stable for long enough to be useful. It doesn't stop them trying though.

A few pages from Chapter 1 of the definitive review of photosynthesis chemistry are online at:
