The main risk of fire from home dryers (and commercial dryers for that matter) is from the accummulation of LINT inside the ductwork.
Gas dryers vent through the same pipe as the lint, and the gas flame provides a source of ignition. As a result the risk of fire with a gas dryer is much higher than an electric dryer, according to the nfpa.
Electric dryers can still cause fires, but the vent has to be significantly obstructed before enough heat is generated to start a fire. The extended drying times that result from an obstructed vent usually cause people to get the dryer repaired before it reaches the point it could start a fire.

∙ 12y agoThe primary cause of dryer fires is excess lint buildup in the vent. To cause a fire, however, both the lint and an ignition source are needed.
In an electric dryer, there is no flame, so either the lint to air ratio must be just right to cause a fire, or the dryer must overheat to the point that it can start the fire. The vent must be nearly clogged for this heat level to occur, and the dryer will stop drying clothes effectively well before this point, so usually the user has the dryer serviced before lint buildup can reach dangerous levels.
A gas dryer generates the drying heat with a flame, and the vent for this flame is the dryer duct - the same duct that is exhausting the lint. The flame is an ignition source, so a gas dryer fire can start with must less lint buildup, given the presence of an ignition source.
The pushbutton igniters have also been a source of problems with gas dryers, and fires often start when the igniter is pushed.

How to Pick the Best Electric Dryers for Your Home?
When you go shopping to pick out a new dryer, you might be overwhelmed by the number of choices available. However, with a basic understanding of the two main types of electric dryers, you'll be able to choose the perfect dryer in no time. The most common types of electric dryers are vented dryers and condenser dryers. Vented dryers expel heat through a venting system that must have an outdoor release. Condenser dryers reuse their own heat, running it through a cycle of steam and water vapor that cools and reheats in order to generate energy. In order to choose the right dryer for your home, you need to determine what kind of system you already have in place, where you want to put your dryer and how much you're willing to spend.It's important to understand what kind of system you already have in place before looking at electric dryers. If you already have a venting system set up, it might be easiest to choose a vented dryer, which will also cost less upfront. However, if you currently have a condenser dryer, it could be extremely costly and difficult to set up the venting system. Typically, it is best to purchase a new dryer that is the same type as the one you're replacing. People who are buying their first dryers should think about whether it would be easier to set up the venting for a vented dryer or the piping needed for a condenser dryer.You'll also need to decide where you want to put your dryer within the house, as this might play a large part in your decision. Vented dryers must be placed near an external wall. They must be able to directly release heat outside through this vent. Condenser dryers offer greater flexibility. When you use this type of electric dryers, you can put the dryer almost anywhere in your house, as long as it has the ability to receive water through a piping system.The type of electric dryers you choose will also be dependent upon how much money you want to spend upfront. Typically, vented dryers are cheaper than condenser dryers. However, they cost more to maintain over a lifetime. Because condenser dryers recycle heat, they use less energy overall. A condenser dryer could be a solid investment that will cut down your heating bills.
