Gas or electric stove: which option is better for the environment? | Your Home More Tech

When we talk about the “hot part” of kitchens, the most common options in the national market are gas stoves, ovens and cooktops, electric ovens, traditional electric cooktops and induction models. Do you know which is the most economical alternative for your pocket? And for the environment, which technology is better, considering the sustainability of our planet?

Looking only at consumption, gas appliances usually spend less than their electrical equivalents, when the bill is converted into cash. And electrical equipment is always priced higher than more traditional alternatives that run on LPG (bottled gas) or natural gas (piped street gas).

While electric ovens and cooktops rely exclusively on electrical energy to function, gas stoves, ovens and cooktops use energy only for the spark that starts the flame.

According to appliance manufacturers and companies in the natural gas industry, a gas oven often heats up much faster than an electric oven. Companies point out that baking a cake or grilling a chicken in a gas oven still costs almost half as much as preparing the same dishes in an electric oven, even with the rise in energy, piped gas and cylinder prices.

Induction stoves and cooktops usually have an advantage due to the efficiency of this technology. They generate heat through electromagnetic waves, which are transferred directly to the pan to promote the movement of food molecules and their heating.

The generation of heat by induction is faster, because the pan heated with the magnetic field receives 100% of the energy generated, without loss to the environment, as is usually the case with the stove flame. Thus, water can be boiled up to four times faster on an induction cooktop or stove than on a gas stove, according to one manufacturer.

Best option for nature

Cooking gas is LPG, which stands for liquefied petroleum gas. This is a gas produced from a mixture of butane and propane, sold in its liquid form in cylinders or cylinders.

Natural gas, on the other hand, is a fossil fuel made from light hydrocarbons, among other various gases, which arises naturally in the environment when fossils are subjected to very specific conditions of pressure and heat, being extracted from perforations in the ground.

According to companies in the sector, LPG has an advantage over natural gas as it does not emit gases that contribute to the greenhouse effect during its combustion.

On the other hand, there are studies that show that gas stoves release pollutants such as nitrogen dioxide and carbon monoxide while we are cooking. These gases are even classified as “probably carcinogenic” in high concentrations or frequent exposure.

Cooking emissions contain small particles known as PM2.5 (particulate matter smaller than 2.5 micrometers). These particles, which also exist in smoke from a forest fire, for example, can penetrate the lung and bloodstream, aggravating cases of asthma and chronic lung conditions. Older and poorly maintained stoves further pollute the indoor air of homes.

Therefore, in our case, as Brazilian consumers, electric stoves, ovens and cooktops turn out to be a better and more environmentally friendly option, in addition to being more sustainable, because our energy is produced in a cleaner and renewable way, mainly in hydropower.

In power plants, energy is generated by the force of water dammed up in dams, which moves turbines when it is released. However, it is necessary to remember that hydroelectric plants can cause serious environmental impacts in the areas where they are built, causing damage to the local fauna and flora and even forcing residents to move from the region.

Clean electricity is electricity that does not emit pollutants into the atmosphere and generates minimal impact in the area where it is generated. The biggest examples are solar power, wind power and hydro power.

In countries where electricity comes from fossil fuels and sources such as coal, electricity has a “dirtier” character, due to gas emissions, air pollution and contribution to global warming in general.

As conscious consumers, we need to remember this information and make the right choices, thinking about our routine, in the short term, and also about the effects on the planet in the long term.

Very soon, smart stoves are starting to reach the national market. These appliances connected to the Internet and integrated into smart homes rely on new technologies and differentials, including for more efficient operation and less energy consumption. Read more here.
