More than half of households have looked at ways to cut their energy use in the wake of rising bills, according to research for the Energy Saving Trust.
A survey of around 2,000 adults found that 53% had considered taking action after reading or hearing about the issue.
A similar proportion (49%) said they were prepared to reduce their usage if it would ensure the UK has enough energy to meet its future needs.
Nearly a quarter (23%) were worried about how the UK would generate enough energy in five years time.
The research, carried out by IPSOS Mori, was revealed at the beginning of Energy Saving Week.
The trust is calling on people to do more to make their homes energy efficient and has produced ten 'top tips' to help cut usage.
Mike Thornton, director of Energy Saving Trust Scotland, said: "Despite all the complexity around the big energy debates, it's important that people focus on what they can do in their homes.
"Pound for pound, using less energy in the first place is by far and away the most cost-effective thing to do and should be the UK's number one priority.
"Through Energy Saving Week we're continuing to encourage households to look at their home and see what they can do to make it more energy efficient in time for winter.
"The higher-cost measures, such as wall insulation, have higher long-term rewards for homeowners, but even small changes around the home - like fitting draught excluders - can make a big difference to energy bills and comfort levels."
Energy Minister Fergus Ewing said: "The Scottish Government is determined to help householders stay warm and reduce their energy bills. Basic energy efficiency measures can make a huge difference to Scottish families who are struggling to make ends meet, allowing them to heat their homes more cost effectively.
"To help tackle fuel poverty, we are actively working with councils and energy companies to ensure that Scotland continues to get its fair share of supplier obligated funding for energy efficiency programmes.
"The Scottish Government continues to provide direct funding to address fuel poverty, committing around a quarter of a billion pounds to it in a three year period."

Dr Sam Gardner, WWF Scotland head of policy, said: "This survey reveals that there is a clear demand from the public for help to cut their fuel bills through improved energy efficiency at home.
"However, the reality is, if Scotland is to meet its targets on fuel poverty and climate change then the Scottish Government needs to offer households much greater support. They could make a welcome start by doubling the proposed budget for energy efficiency in our homes.
"Doing so would deliver warmer homes and cheaper energy bills for households whilst also helping to cut carbon emissions."
