I would hope that they'd be coming at renewable energy from the other direction to us, as the way for them to have a sustainable industrial revolution. On the other hand it's possible that wouldn't have happened, and quite likely that it won't happen for another century or few.
What won't have happened in that world is an industrial revolution based on steam engines, which make very inefficient use of combustion energy. With only wood and charcoal to use, steam won't replace water- and wind-mills as mechanical motive power, and the industrial revolution will be delayed.
What I hope will happen is that the values of the Enlightenment will still be at work, and scientific enquiry into the propreties of magnetic and electrical phenomena will find their Faraday, Maxwell, and Tesla and Edison. The electrical generator and the electric light-bulb and the lead-acid battery will be invented, the generators being powered by water-wheels and windmills, and later by water turbines and (small) dams. It will happen, given that prior to the light bulb, they don't even have gas-lights, just (vegetable) oil lamps and tallow candles.
Once they have utility electricity for lighting, low-powered electric gadgets will follow, and the spirit of scientific enquiry will start investigating what electricity is actually made of. Electric motors will give them vacuum pumps. The electron will be discovered. Then the thermionic valve, and radio.
Where I'm not so sure is whether they'll yet have scaled up hydro-power to large hydroelectric dams. The engineering princuples are obvious, but you'd have to burn a lot of trees to make enough concrete and iron rebar to build a large dam. That might hold things back until someone very rich was convinced that the huge investment was justified.
Meantime, in the research labs, will someone have found how to make a decent solar cell? That's their next key development, if they are to reach our level of technology. Once they can harvest sunlight without the inefficiencies of plantlife, they'll have all the electricity they can use. (The Earth's current electricity requirements could be satisfied by covering less than five percent of its deserts with solar panels). En route, they may have discovered solid-state electronics, but if they come at solar cells via chalcogenides or tellurides, maybe not yet. (These are easier than ultrapure silicon in a society with much higher energy costs than our own).
I don't think they'll have obtained practical nuclear power yet, unless their planet is younger than ours (naturally fissile Uranium without enrichment). Uranium enrichment requires prodigious amounts of electricity in, before you have enough sufficiently enriched uranium to get started. In our world, it was probably WW2 and the cold war which made nuclear power happen (as a side effect of making atomic bombs). In a lower-energy world, world wars would probably lie in their future not their past. (Mind you, small wars are no less deadly if you are fighting one).
