Is the Sun weaker at higher latitudes?

Matt | Model Concepts  asked the Naked Scientists:
Hello Chris,

I spent six years in the UK and constantly craved the sun. What I can't understand is why in the higher latitudes, I can't FEEL the sun in winter. I always thought it was because of the earth's tilt and therefore distance to the sun, but if the earth's orbit is elliptical then isn't such a small distance irrelevant in this topic?

Love your programme. You guys rock.

What do you think?

sunlight is spread over a larger area at the poles, and has to travel through more energy-absorbing atmosphere, than at the equator ...
