Issue 127 April-June 2014 is out now! As always, ReNew comes overflowing with articles to satisfy both the technically and the not-so-technically minded. Regardless of whether your interest is photovoltaic cells, recycling, or even environmentally responsible building techniques, there is something for you in this issue.

ReNew 127 has ‘keeping warm’ as its focus. Inside you’ll find:

  • Who needs fossil fuels? (part 2)

    Energy will flow from the sun, the brakes and even the shock absorbers in the SolarX solar car, writes Clint Steele.

  • Sourcing green products

    There are ways to stop the ‘too-hard’ feelings when choosing green building materials, writes Elizabeth Wheeler.

  • Enter the eco-city

    Peter Reefman takes us on a tour of China’s amazing and vital eco-cities

  • Cash flow

    Which water saving technologies also save money? The ATA reports.

  • Rainwater harvest: keeping it clean

    Dennis Boon describes best practice to keep your tank water clean.

  • Winter comfort: not just a heater choice

    There’s more to consider than just the choice of heater when aiming for winter comfort. Alan Pears searches for the ideal solution.

  • Cool-climate build

    Designing a house to be as energy efficient as possible is one thing; actually achieving this can be another task altogether. Meg Warren and Fraser Rowe describe their building challenges and eventual rewards.

  • Fresh air without the heat loss (or gain)

    As we seal up our homes for better energy efficiency, mechanical ventilation becomes important, writes Clare Parry.

  • Mind the gap

    David Coote is on a mission to increase the energy efficiency of his house as well as provide a road map for others to follow. Here, he looks at the (lack of) data available and one approach that does help: a draught-proofing audit.

  • Case study: the benefits of insulation

    Richard Keech found many hidden benefits from plugging the last thermal ‘hole’ in his house

  • Insulation buyers guide

    Is your home hot in summer and freezing in winter? Lance Turner takes a look at how insulation can help fix these problems.

  • Low-power, low-cost computing

    If you need to be energy frugal, you can still have a real computer for real tasks that won’t cost the earth. Lance Turner shows you how.

  • DIY solar hydronic

    Chris Hooley describes his experiment with building a solar hydronic heater.

  • Product review: pellet heater

    Many people in rural areas use wood heaters, but there are cleaner options. Lance Turner looks at a heater that can use several different fuels.

  • The Pears Report: Peak demand and ‘enoughness’

    Why should we expect unlimited access to energy when we can take responsibility for how much energy we use, asks Alan Pears.

  • Salvage It: Espresso coffee machines

    See an espresso coffee machine being thrown away? Grab it, writes Julian Edgar!

  • Member profile

    Stephen Whately is ReNew’s dedicated proofreader and ATA member. He talks to Beth Askham about his favourite places and zero carbon house.
