So are you asking for a list of ways that global warming can be avoided -- technologies that can help avoid global warming?  If so, here are some examples:

  • Hybrid cars that use batteries as well as gas and thereby get better mileage.
  • Wind turbines to create electricity without burning fossil fuels.
  • Technology to inject carbon dioxide into rock formations rather than releasing it into the atmsophere.
  • Technology to create biofuels -- like using algae to create fuel.
  • Better battery technology so that energy captured from the sun, for example, can be stored until needed.

I am assuming that you are looking for a list of ways to avoid global warming.  One thing to keep in mind is that global warming is most likely already here.  So in reality we can't avoid it, but we can slow it down.

One cause of global warming is deforestation.  Deforestation is "the removal of trees without sufficient reforestation.  This has resulted in damage to habitat,  biodiversity loss and aridity. It has adverse impacts on biosequestration of atmospheric carbon dioxide.  So if deforestation is one cause of global warming you could plant trees or roof top gardens.

Continued recycling of waste will help prevent global warming.  Using old things in new ways instead of creating tools from the environemt can assist with helping the environment.  

Using public transportation is another way to slow down global warming.

The biggest causes of global warming include release of carbon dioxide and some other gases by burning of fossil fuel. These gases damage the ozone layer causing the global warming. Another major cause of global warming is the reduction area of forest cover on the earth. The forests and other vegetation reduce the temperature of earth by directly absorbing the energy of sun in the process of photosynthesis. These also absorb the carbon dioxide gas in the photosynthesis process, reducing the level of its concentration in the atmosphere. Thus the measure for reducing global warming need to target reduction in release of harmful gases by burning of fossil fuel, and increasing the forest cover.

The forest cover can be increased by avoiding cutting of forest for industrial, agricultural and urban development activities. Also, plantation of trees can be taken up to replenish the reduction in forest cover.

The emission of carbon dioxide and other harmful gases by burning of fossil fuel can be reduced or controlled by several means. These include:

  • Reducing the total consumption of energy that requires burning of fossil fuels. For example, accepting lower temperature to reduce energy used for heating of homes and other premises, and using public transport for travelling rather than using personal cars.
  • Reducing consumption of energy by using more efficient processes.
  • Reducing content of harmful gases in exhaust created by burning of fossil fuel by better technology. This include technology that reduces the quantity of fuel burnt, as well as treating the exhaust to reduce harmful ingredients.
  • Using renewable and other alternate sources of energy that are less polluting.

1. Reduce, Reuse, Recycle

Do your part to reduce waste by choosing reusable products instead of disposables. Buying products with minimal packaging (including the economy size when that makes sense for you) will help to reduce waste. And whenever you can, recycle paper, plastic, newspaper, glass and aluminum cans. If there isn't a recycling program at your workplace, school, or in your community, ask about starting one. By recycling half of your household waste, you can save 2,400 pounds of carbon dioxide annually.

2. Use Less Heat and Air Conditioning

Adding insulation to your walls and attic, and installing weather stripping or caulking around doors and windows can lower your heating costs more than 25 percent, by reducing the amount of energy you need to heat and cool your home.

Turn down the heat while you're sleeping at night or away during the day, and keep temperatures moderate at all times. Setting your thermostat just 2 degrees lower in winter and higher in summer could save about 2,000 pounds of carbon dioxide each year.

3. Change a Light Bulb

Wherever practical, replace regular light bulbs with compact fluorescent light (CFL) bulbs. Replacing just one 60-watt incandescent light bulb with a CFL will save you $30 over the life of the bulb. CFLs also last 10 times longer than incandescent bulbs, use two-thirds less energy, and give off 70 percent less heat.

If every U.S. family replaced one regular light bulb with a CFL, it would eliminate 90 billion pounds of greenhouse gases, the same as taking 7.5 million cars off the road.

4. Drive Less and Drive Smart

When you do drive, make sure your car is running efficiently. For example, keeping your tires properly inflated can improve your gas mileage by more than 3 percent. Every gallon of gas you save not only helps your budget, it also keeps 20 pounds of carbon dioxide out of the atmosphere.

5. Buy Energy-Efficient Products

When it's time to buy a new car, choose one that offers good gas mileage. Home appliances now come in a range of energy-efficient models, and compact florescent bulbs are designed to provide more natural-looking light while using far less energy than standard light bulbs.

6. Use the "Off" Switch

Save electricity and reduce global warming by turning off lights when you leave a room, and using only as much light as you need. And remember to turn off your television, video player, stereo and computer when you're not using them.

It's also a good idea to turn off the water when you're not using it. While brushing your teeth, shampooing the dog or washing your car, turn off the water until you actually need it for rinsing. You'll reduce your water bill and help to conserve a vital resource.

7. Plant a Tree

If you have the means to plant a tree, start digging. During photosynthesis, trees and other plants absorb carbon dioxide and give off oxygen. They are an integral part of the natural atmospheric exchange cycle here on Earth, but there are too few of them to fully counter the increases in carbon dioxide caused by automobile traffic, manufacturing and other human activities. A single tree will absorb approximately one ton of carbon dioxide during its lifetime.

8. Encourage Others to Conserve

Share information about recycling and energy conservation with your friends, neighbors and co-workers, and take opportunities to encourage public officials to establish programs and policies that are good for the environment.
