Dr David Clubb, director of RenewableUK Cymru says support for all types of renewable energy, including onshore wind farms, is evident from today's poll, but Wales is still lagging behind other countries in the UK and Europe.
Over two thirds of people in Wales are in favour of large scale wind projects in their local area.
That's according to a YouGov survey commissioned by Renewable UK Cymru into attitudes of Welsh people towards renewable energy.
Almost two thirds (62%) of the people questioned for the annual survey said they support the development of wind power as part of a mix of renewable and conventional energy.
The survey shows that support for renewable energy outshines conventional fossil fuels.
Just 22% of people were in favour of shale gas and 31% for nuclear to provide energy in their area.
The highest support was for solar energy, with 81% of people showing support for this.
The developer RES says it is "disappointed" by Powys County Council's rejection of its plans to build a wind farm at Garreg Lwyd Hill in Radnorshire.
It said the wind farm would have provided a "safe, secure and low-carbon source of electricity" and "brought benefits to the local community."
Powys County Council has refused plans for a wind farm near Llanbadarn Fynydd, in Radnorshire.
Developer RES says the Garreg Lwyd Hill Wind Farm proposal consists of 23 turbines, at a maximum height of 126.5m, which would generate enough electricity to power more than half of the homes in Powys.
It is located within an area designated by the Welsh Government for renewable energy development.
Members of the authority's planning committee have unanimously voted to refuse consent to the application today.
The UK Government has granted approval for the building of a controversial wind farm in Carmarthenshire.
The Brechfa Forest West Wind Farm will consist of 28 turbines up to 145 metres tall. It will have a capacity of between 56 and 84 megawatts.
Local people have opposed the RWE npower development, saying it will ruin the area's ecology and landscape.
