The widespread impact of even small scale energy efficiencies in technology use are being highlighted in the latest modelling by the Energy Efficiency and Conservation Authority. Installing things like LED lighting, and high-temperature heat pumps could save the equivalent of 4,000 gigawatt-hours of electricity - about 10 percent of current annual demand. EECA says the usual mind set is to build more renewable generation, but investment in energy efficient technology is often overlooked. And it warns that overlooking this creates a risk that we might build more generation than needed, resulting in higher than necessary costs. Meanwhile the Government is looking at energy efficiency ratings for its offices. Kathryn Ryan talks to EECA's Chief Executive Andrew Caseley.

July 19 marks 100 years since Sir Edmund Hillary was born, and the start of a month of activities to celebrate his life and achievements. Prime Minister Jacinda Ardern will host an event at Parliament next week at which Poet Laureate Selina Tusitala Marsh will perform her new poem about Sir Ed called Hillary's Step, New Zealand Post is issuing commemorative stamps, and a full-length symphony entitled Roar of a Thousand Tigers will be premiere in Christchurch at the end of the month. One of those who knew him well was Tom Scott, a member of the Hillary Centenary Steering Committee which is organising the events. He joins Kathryn to talk about what they've got planned to mark his remarkable life.

Award winning British sports journalist and author Ed Hawkins' new book explores the sometimes bizarre "cosmic" side of sports among a group of new age thinkers in the United States in the 1960s - athletes and coaches convinced that using no more than the power of their own minds, they could be bigger, faster, more accurate or able to control their opponents minds. Ed is well known for his book Bookie Gambler Fixer Spy which lifted the lid on India's illegal bookmaking industry and for his expose of the trafficking of African football hopefuls in The Lost Boys.
