Christians urged to switch to greener energy providers
A new campaign has been launched encouraging Christians to change to an electricity supplier who only uses renewable energy.
The Big Church Switch has been created by Christian Aid and Tearfund and will invite hundreds of thousands of Christians to switch energy suppliers.
Churches will also be encouraged to make the change.
The Big Church Switch said it would offer "a very practical way to channel consumer power to renewable energy and show the government that clean energy must be central to the effort to address climate change".
A new website will provide information for people considering making the switch.
The Bishop of Salisbury Rt Revd Nicholas Holtam, who leads on environmental issues for the Church of England, said: "The Big Church Switch is a simple, practical, good idea.
"It supports the move to renewable energy.
"If Lent is about renewing our lives in response to the love of God here is a way to follow.
"You can do it, and so will I."
Ben Niblett, Tearfund's Senior Campaigne, said: "Tearfund are excited about the Big Church Switch. The UK church has a vital role in overcoming poverty and inequality in a way which doesn't cost the earth and lasts for generations to come.
"Switching is a great way for Christians to love our neighbours and show the government we want more action on climate change, like investment in clean, renewable energy.
''Christians care about our neighbours in the UK and around the world being hit by climate change - we're seeing more floods, more droughts, and more people going hungry - so we think this will strike a chord.''
Christian Aid's Head of Advocacy, Laura Taylor, said: "The public want clean energy and are willing to take action themselves by switching suppliers.
"But to make the big shift to a low carbon future happen, individuals and communities can only do so much before it's up to the Government to change the whole system and drive the energy market to 100% clean energy.
"So today we're saying to the Government: we're switching to low carbon energy, now you must switch the country's energy from fossil fuels to renewables."
