How much do electric vehicles help the world? I guess that they are a great thing for the world, even if it harms the environment some with the manufacturing of the device for the cars.
There is zero pollution when they are on the streets and that is a substantial thing.
As for the device in homes that keeps us comfy, let us talk a bit about it. Heating, Ventilation and A/C technology has a significant impact on the environment, as it consumes a big amount of energy and emits greenhouse gasses. Heating, Ventilation and A/C is used to regulate the temperature, humidity, and air quality of indoor spaces. Heating and cooling are the primary functions of HVAC systems, and they are responsible for the majority of the energy consumption. The energy used for heating and cooling is often generated by burning fossil fuels, which emit carbon dioxide and other greenhouse gasses into the atmosphere. These emissions contribute to temperature change and global warming, which have far-reaching impacts on the environment, including rising sea levels, more frequent and drastic weather events, and loss of biodiversity. In addition to energy consumption, HVAC systems also impact the environment through their use of refrigerants. Refrigerants are chemicals used in air conditioning and refrigeration systems to cool and dehumidify air. Some refrigerants, such as chlorofluorocarbons (CFCs), were found to be harmful to the ozone layer and were subsequently phased out. However, several of the up-to-date refrigerants still have a high global warming potential and can contribute to temperature change. So, Heating, Ventilation and A/C technology has a significant impact on the environment, primarily through its energy consumption and refrigerant use. However, with correct design, replacement, and repair, the environmental impact of Heating, Ventilation and A/C systems can be minimized.
