From 8 to 9 pm local time tonight, millions of people will be switching off the lights and joining with their neighbors to remind us all to conserve energy. Because we're so used to having the lights and television on, here are 10 things you can do to while away the time courtesy of the World Wildlife Fund.

1. Host a Green Party
Get your friends together for an Earth Hour eco-party. Fire up the flashlights and battery lanterns, serve organic food, avoid the disposable utensils, use natural décor (like flowers and hanging plants) and have a friend provide acoustic music. Talk to your guests about how you're each reducing your environmental footprint and share ideas and solutions for saving more energy, money and carbon dioxide.

2. Give Yourself an Energy Makeover
Use Earth Hour to make your home more energy efficient: Replace your old light bulbs with compact fluorescent bulbs; install power strips (so you can turn computers and electronics on and off more easily); and change your air conditioner filters. Or go one step farther and install one new energy-efficient item, like an EnergyStar qualified DVD player. And on Monday, call your local utility and sign up for green power-like wind, hydro or solar.

3. Go Green with Your Kids
Earth Hour is a perfect time to talk to your kids about the environment and why we need to protect our planet from the dangers of climate change. Check out books on the environment from the library and read by flashlight, or head into the yard and have a night picnic. Or how about a night of board games? Check out our downloadable Earth Hour kids' activities.

4. Do a Recyclables Scavenger Hunt
Get your flashlights and scour your cabinets and shelves for cans, bottles and cardboard (like cereal boxes) that you don't normally recycle. Make a list of all the non-recyclable containers you're using now (like plastic shopping bags and butter tubs), and figure out ways to reduce your consumption of items that end up in landfills. One easy tip: get reusable grocery bags... and reuse them!

5. Green That Workspace!
Working the night shift? Even if you can't turn off all the lights at work, look around and see what you can unplug, turn down or use less of (like consuming less paper by printing double-sided). Every day millions of computer screens and speakers are left on overnight--shut 'em off! And talk to your coworkers about what they can do to help make a difference, too.

6. Involve Your Local Leaders
If your city or town isn't hosting an Earth Hour event, ask your local government to set up a community "green" discussion this spring. Help organize attendance by reaching out to local environmental and community groups, and come prepared to ask your leaders what they're doing to make your city greener.

7. Clean Up Your Neighborhood
Grab a flashlight and take a long walk through your neighborhood, picking up trash and recyclables as you go. It's a great chance to do some stargazing, too!

8. Unplug and Chill Out
Most of our daily activities--like watching TV, shopping online and texting friends--require loads of electricity, but do we really need to do so much stuff all the time? Take one hour for yourself to just chill... turn off the screens, put down the handheld devices and just take some "you" time to reflect, read or talk to your family. After all, why do more when you can do less?

9. Take Your Temperature
Your thermostat and your refrigerator are responsible for a huge portion of your carbon footprint. If you lower your thermostat by just 2 degrees and set your fridge to 37 degrees F. and the freezer at 0 degrees F., you'll make a big difference.

10. Make a Pledge for the Planet
Earth Hour shouldn't end at 9:01 pm--it's a chance to take a first step toward lowering your overall impact on the environment. So use part of that hour to make a personal pledge to do more--recycle, drive less often, turn off or unplug electronics, and beyond. The only way we're going to stabilize our climate is if we make real changes in our everyday lives. That change begins with Earth Hour, and ends with a healthy planet.

Representatives Henry Waxman and Edward Markey have introduced a new bill that strictly limits how new coal-fired power plants are being built. From their announcement:

"Comprehensive economy-wide regulation to address global warming is coming soon," said Rep. Waxman. “But new uncontrolled coal-fired power plants are being built today. My legislation says: “No new plants without emissions controls.” The alternative is senseless - locking in decades of additional global warming emissions and requiring greater emissions reductions across the U.S. economy to compensate."

"If we lose control of coal, we will have lost control of the climate," said Markey, Chairman of the House Select Committee on Energy Independence and Global Warming. "This bill will make companies prepare for the future and prevent them from building low-tech coal-fired power plants before a global warming bill is passed that will necessitate the use of the newest, most climate-friendly technology. "

Without emissions controls, a new coal-fired power plant will emit hundreds of millions of tons of global warming pollution over its fifty-year lifetime. Over 100 new plants have been proposed, and even if just a portion of these are built, they will emit over a hundred million tons of carbon dioxide a year. One of these plants alone could offset the reductions that will be achieved through the Northeastern states' Regional Greenhouse Gas Initiative.

The bill places a moratorium on either EPA or states issuing permits to new coal-fired power plants without state-of-the-art control technology to capture and permanently sequester the plant's carbon dioxide emissions. The moratorium extends until a comprehensive federal regulatory program for global warming pollution is in place.

The bill also bars a new coal-fired power plant without state-of-the-art control technology from receiving any free or reduced cost emissions allowances under a future federal program to address global warming.

While it's not an outright ban on new coal-fired power plants, it may work out to becoming an effective ban. Companies are not going to want to build coal-fired power plants when the costs of meeting these strict requirements are so high.

An outright ban on coal power plants, while it would be the most desirable action, isn't likely to pass either the House or Senate. As it is, this bill is going to have a long, hard fight in order to make it to the President's desk. And I highly doubt the President will sign such a strongly worded bill.

But more often than not, legislation of this type takes three or four attempts before it becomes law, and with a new President in office in less than a year, chances are it's only a matter of time before coal goes away forever.

Keep in mind, however, that while people may not be totally against coal-fired power plants if they're permanently sequestering CO², there are still a lot of coal mines out there wreaking havoc on the environment. The only long-term solution is an outright ban, but I don't have a problem taking small steps towards that goal when the opportunity presents itself

The bill itself hasn't been assigned a number yet, and it isn't listed at the Library of Congress yet, but you can read the text of the bill as it was introduce here (pdf).
