A quarry? Pickaxes should work, and you can use electrical engines to power quarries, as well as Redstone Energy Cells. Many use Energy Tesseracts, and it's possible to send liquid to Magmatic Engines to power it. Steam engines are a good first engine, with 2 mj/t and running on coal, it'd be easy to power them. You can also power them with a straight up boiler, and combustion engines are tried and true.
But there are TONS of ways to power quarries, they'll take up to 48mj/t, so mixing any of the above methods (and more) would do nicely.
But if you're just starting, a few steam engines (from TE) should do the trick.
