I also heard there is no noticable difference between 1080i vs 720p when your set less than 50"
Answer
LCD - This is the everyman HDTV. Its mass produced, cost effective, low on power consumption, and just what people "know." LCD monitors in computers make it a more familiar product for many. Its SD playback tends to be a bit sharp/crisp; think the evening news (this isn't good vs bad, this is personal taste). Its colors tend to be a bit more muted (again not good vs bad, just taste). LCDs have a matte finish for the viewing surface (the edge around it can be glossy though depending on model).
LCD's are inherently bad with motion playback. The suffer from motion blur (ghost trails). This is why you see "better" ones advertised with 120Hz or 240Hz refresh rates. The improved refresh rates are an attempt to overcome that inherent flaw.
LCD's will give you weaker blacks, colors, and contrasts on the whole. This is why you see the proliferation of the LED LCD. That technological step alleviates those LCD problems.
Plasma TVs inherently give you better blacks, colors, and contrast. They are also inherently strong in motion playback as their refresh rate is near instantaneous (like a CRT). Plasma colors tend to have more pop to them (not good vs bad, just taste). Plasma SD tends to be a bit softer (think Hollywood films); again not good vs bad, just personal taste.
Plasmas should be conditioned though. For the first 100-200 hours of operation you want to keep the contrast and brightness cranked way down. Then optimize and enjoy. This isn't necessary persay, but most "nerd" consumer groups will tell you to do it for paranoia sake.
Plasma TVs are a shiny finish though, so in rooms with light control problems that finish can create reflection problems. Plasma technology on the whole does use more power than LCD. But not all models are made equal, so one must do some homework. And worst case scenario, a "very bad" Plasma TV would likely only cost you $40 more per year in electricity bills (and again not all models are made equal).
Plasma myth (1) - They experience burn-in. This is inaccurate, those days are gone. Just condition the gasses and then use it as normal and you're fine. Also, the better sets have built-in features to prevent this (on top of the technology just generally being better now than say 5 years ago).
Plasma myth (2) - They have short life spans. This is another inaccuracy. Most are now rated in the 60,000-100,000 hours range. At 8 hours a day 365 days a year that would mean a life of 20-30 years. So do you think you'll still want/own the same TV in 15 years, let alone 30?
Plasma myth (3) - They won't work in high altitude because of problems for the gasses. This is again no longer an issue. Current Plasmas can be purchased and used in mile high Denver, and above, so you'll be fine where ever you are (unless you're living in the Himalayas).
720 vs 1080 - There is no set size on when it matters. Typically though its though that anything under 40" definitely doesn't show any of the advantages of 1080. 40" - 50" is the grey area where some argue it matters and others say maybe a bit or not so much. 50" and above you definitely want native 1920x1080 resolution for your TV, as the advantages will become noticeable.
Damn almost forgot... DLP Rear Projection. The image quality, on all levels, is fairly close to Plasma. It would be at par with it if it wasn't a dying technology. Mitsubishi is the last developer of the technology after Samsung recently announced they were giving up on it. So Plasma is just getting more R&D and advancements than DLP. That said though DLP is still a rock solid image.
Its often joked that DLP will be the last TV you ever own. That refers to the expectation that the TV will still work until its actually physically falling apart (decades). But the bulbs in it need to be constantly replaced. Depending on the bulb and your TV usage, it could last anywhere from 1 year to realistically 4 years. Replacing is something you can do on your own easily enough. A new bulb though costs $200-$250 or higher. Also, some sets have air filters that you should clean every month or two. So there is certainly an inconvenience factor in owning the sets.

Do they make anything like this?

I am interested in becoming more eco-friendly and I was just wondering if they have solar lights that light your walk ways at night is there such a product that can do the same for the inside of your house? Say that you place your bulbs outside to soak up all the solar energy then use them at night. Do they have anything like that or is that just something I wish they had cause I am tired of an electric bill?
Answer
Indoor solar lights would be a little impractical. Most of the outdoor solar lights that are reasonably priced aren't very bright, they are used more as walkway lights than task lighting. The bulbs don't charge, they have little solar panels. It would likely be much less expensive to change bulbs to CFL's or LED's. A CFL uses about 1/4 and an LED uses about 1/10the electricity of an incandescent.
Here are some more tips on reducing your utility bill.
It is about awareness. Learn how much energy you are using and how you are using it. Many cities or utilities have free energy audits, often they will come to your home and show you ways you can reduce your energy usage.
Help your heater by keeping the warm air in, weather strip and caulk doors and windows, seal off vents and other large gaps. Use heavy drapes over windows. Adjust your thermostat a few degrees, there is nothing wrong with wearing a sweater inside. A programmable thermostat can save money and make the home more comfortable. Many people crank the heat up while they are getting ready in the morning only to leave the house after it gets warm.
Replace appliances with energy efficient models when you need new ones. Even older ones can be used more efficiently, only wash full loads, line dry when possible, don't over dry clothes and make sure the vent is clean. You can wash fewer clothes by wearing things more than once, I wear my jeans a few times before they hit the hamper. Hanging up clothes that were worn for a brief time or only tried on will stop clean clothes from getting mixed in with the dirty.
If you are replacing lighting look for fixtures with fewer bulbs, and if you hate the look of CFL's look for fixtures that will hide them. There are a wide range of CFL's with various strengths and colors of light, try a few to see what works best in various rooms.
Standby energy can be up to 15% of your bill. Not all appliances use energy when they are turned off, but most electronics do as well as anything with a light or clock. Many chargers use energy even when nothing is attached. I use a power strip with a switch for my tv, dvd and game system and for my desktop, speakers and monitor. After I turn things off I flip the switch and stop using standby energy. I also unplug chargers and ipod docking stations when not in use.
