Besides the cost savings, there are also significant environmental benefits in terms of vehicle emissions as shown in the table below. In addition, electric vehicles are much quieter at lower speeds. ]

* if from waste cooking oil then fewer emissions
Finding a use for waste products such as used cooking oil can not only create local jobs but it can also reduce the difficulty of disposing of waste products. Used oil can block drains, while methane from landfill and slurry is a much more potent greenhouse gas than carbon dioxide. Dependence on oil tends to be considered only on the occasions when there is the shock of queues outside the petrol pumps and the uncertainty whether you are going to be able to fill your car up the next time you run low on fuel. Research called Oil Vulnerability Audits highlights the risks to businesses in the short term from spikes in the price of fuel as well as longer term challenges. Moving beyond oil helps increase the resilience of your local community and economy.
