Yesterday I mentioned the role of the gases linked to climate change in causing acidification of the oceans and how it could wreck the food chain. I mentioned the potential economic consequences in Queensland of not doing more to protect the oceans.
Now United States President Donald Trump has walked away from the Paris Climate Accord. Citing the supposed economic toll to the United States if it continues working on the Accord, the United States Government has shown its preference for fossil fuels at a time when major in roads are being made into renewable fuels, more efficient methods of electricity generation and the rise of the electric car. Mr Trump has demonstrated a callous disregard for an environmental crisis where the overwhelming majority of scientists believe gas emissions from excessive fossil fuel burning is the cause of a major rise
But not all is lost. Even as the United States Government refused to have any more to do with it, a revolt is spreading across America. 61 cities decided to support the Paris Climate Accord anyway. On the world stage other big players including China, the European Union and even Australia – better known for deriding the Paris Climate Accord and the preceding Kyoto Climate Protocol – stepped up and indicated they would honour their commitments.
In New Zealand, despite the mediocre efforts made by this Government to date and the inability of the Opposition to gain traction in Parliament, the commitment to reduce our contribution to the greenhouse gas emissions equation has not changed. In terms of going forward, I believe there are a significant range of energy sources that New Zealand could be significantly investing more into. Namely:
- Tidal power
There are also a number of steps that could be taken to reduce the power footprint in New Zealand.
A Green audit done over a decade ago suggested that between 15-20% of New Zealand’s power usage was avoidable. If that is still the case today, with an installed generation capacity of 9637 megawatts, between about 7700 and 8200 megawatts would be needed if all of this could be saved.
Another step that could be taken is retrofitting. Retrofitting all large facilities such as hospitals, University buildings, airports with energy saving mechanisms such as automatic sensors which turn lights out after a certain time. If this were done with an incentive such as being able to keep the savings made by such investment, these would pay for themselves fairly quickly.
A third step that could be taken is enabling individuals who want to contribute power to the grid to do so without punishment. In January the Electricity Authority ruled against Solar Energy New Zealand, which had complained about the tariffs imposed by Unison Network Limited on retailers with residential customers on S.E.N.Z.’s network.
But overall there needs to be a blue print that could have been finished by now for looking forward into the future. We as a nation need to reduce our gas emissions just as we need to tackle the acidification from the ocean that is also aggravated by these gases.
