stratus, battery light, high revving

So I get in my car and start driving, I notice the battery light comes on, and when I accelerate the power slightly cuts out. When I put the clutch in it stays revved up high, and slowly comes down. This all happened at once. So I have no idea what the heck it could be. I drove it the next day and my windows rolled up slowly and lights were dim, so there seems to be something wrong with the charging system. Its the high revving and cutting out that I cant explain.

Anybody had similar experience or know what this could be?

Thanks
