Heater can run off of propane, wood or diesel. AC just forget about, use small fans and proper ventilation. Lights can be done with LEDs that just sip small amounts of power. The phone is also a real low power draw for charging.

For a computer look at netbooks and tablets. They both use very small amounts of power. The TV/DVD will use more power, but look at LED LCD TVs and they don't use a lot of power, actually. My 24 inch TV only draws 40 watts and is a nice 720p HD TV. As for the DVD, you can just use your netbook with HDMI out.

The fridge is a larger power draw, but there are efficient options out there and you can save power just by turning it down some. Cool beer with a lovely view beats cold beer while stuck on land.

No one can really ballpark anything though because it depends a lot on your boat's design and how you decide to build things out. Is there room for solar without an arch? Is there space for a diesel heater and maybe a generator?

You need to narrow down your specific needs, get an idea about how much each system will draw in power and then decide how to best outfit to get you by.
