ALL new public buildings will be made energy-efficient in a drive launched by Kirklees Council.
A town hall leader declared: "The future is green."
Political chiefs have ordered that 30% of power consumption in the council's new projects must come from green, renewable sources by 2011.
Council Cabinet member Clr Andrew Cooper said: "This will impact on every residential home, every children's centre and every school we build.
"This policy ensures a new high standard for buildings in the future."
Renewable energy includes solar panels, wind turbines and boilers using non-fossil fuel, such as wood pellets and vegetable oil.
Clr Cooper called it a ground- breaking policy which would save tax money for years to come.
He added: "As conventional fuel prices for gas and oil rise, renewable energy not only becomes more cost- effective it also becomes the most cost-effective way to provide heating and lighting for buildings.
"With buildings we construct today having to last upwards of 50 years we have to consider not only the cost of fuel today but the likely rise in costs in future years.
"Investment in renewable energy is not only good news for the council taxpayers of today but also in the years to come."
