Australia’s urgent need for long-term planning on energy, especially on energy efficiency

Gas crisis? Energy crisis? The real problem is lack of long-term planning, The Conversation,  Senior Industry Fellow, RMIT University, March 20, 2017 “……The long view

When we consider the long term, we must recognise that we need to slash our carbon emissions. So coal is out, as is any overall expansion of natural gas production.

Luckily, we have other affordable long-term solutions. The International Energy Agency, as well as Australian analysts such as ClimateWorks and Beyond Zero Emissions, see energy efficiency improvement as the number-one strategy – and in many cases, it actually saves us money and helps to offset the impact of higher energy prices. Decades of cheap gas and electricity mean that Australian industry, business and households have enormous potential to improve energy efficiency, which would save on cost.

We can also switch from fossil gas to biogas, solar thermal and high-efficiency renewable electricity technologies such as heat pumps, micro-filtration, electrolysis and other options.

Renewable energy (not just electricity) can supply the rest of our needs. Much to the surprise of many policymakers, it is now cheaper than traditional options and involves much less investment risk. Costs are continuing to fall.

But we need to supplement renewable energy with energy storage and smart demand management to ensure reliable supply. That’s where options such as pumped hydro storage, batteries and heat-storage options such as molten salt come in.

This is why the crisis is more political than practical. The solutions are on offer. It will become much more straightforward if politicians free themselves from being trapped in the past and wanting to prop up powerful incumbent industries. https://theconversation.com/gas-crisis-energy-crisis-the-real-problem-is-lack-of-long-term-planning-74705
