Top 15 Renewable Energy Companies in New Zealand


New Zealand is one of the world’s most beautiful as well as peaceful countries. The country is also known as an island country because it consists of two main landmasses; the North Island and the South Island. Plus, let’s not forget to mention it’s other more than 700 smaller islands. But the question remains, how evolved New Zealand is when it comes to renewable energy. Let’s see the top renewable energy companies in New Zealand.


When calculated, New Zealand’s 40% of primary energy comes from renewable energy sources in 2018. Likewise, 80 percent of electricity comes from renewable energy sources in New Zealand. In this number, hydropower covers 70 percent while geothermal power covers the remaining 10 percent of electricity generation.

However, to take the electricity generation from renewable sources to 100 percent, the Government of New Zealand plans to add electricity generation from biomass resources. Furthermore, the country is rich in geothermal energy resources because it consists of many volcanic areas. Similarly, the country is taking necessary steps towards carbon neutrality by 2050. This is under the 2019 Zero-Carbon Bill as well as a broadened NZ emissions Trading Scheme.


Furthermore, different studies from experts have shown that it is technically feasible to provide 100% of electricity demand from renewable energy sources only. This is without any risk of shortages in energy supply.

What is New Zealand’s main Source of Energy?


Even though New Zealand’s renewable energy development is praiseworthy, its consumer energy demand is still saddening. The consumer energy demand for Oil is higher than other energy sources. So, New Zealand’s main source of energy automatically becomes oil which is a non-renewable resource. The below table shows the consumer energy demand.



Oil

48 Percent

Electricity

24 Percent

Gas

12.5 Percent

Other renewables

9.7 Percent

Geothermal 

1.3 Percent

Coal

4.1 Percent


The country’s Total Primary Energy Supply or TPES in short is generally measured in Petajoules (PJs). The primary energy supply was 819 PJs in New Zealand. In this number, Oil contributed the highest with 307 PJs.

How much of New Zealand’s energy is renewable?


As we previously said, approximately 40% of primary energy comes from renewable energy in New Zealand. However, approximately 80% of electricity comes from renewable energy. Thus, when talking about Total Primary energy the ratio is split 40/60 with oil and coal taking the number 60. But in terms of electricity only, the number is split 80/20 with hydro and geothermal taking the number 80 whilst 20 is taken by coal only.


Furthermore, New Zealand is a net importer of energy, mainly when it comes to petroleum products. However, the proportion of non-renewable energy varies annually which depends on water flows into hydro-electricity lakes as well as demand for energy. As we earlier discussed, energy demand for oil is the highest in New Zealand. Therefore, it contributes hugely towards 60% non-renewable energy sources.

New Zealand Total Energy Consumption


Likewise, another source used is coal that is produced from 18 opencast mines. Similarly, high in demand oil and gas is produced from 21 petroleum licenses all in the Taranaki Basin. Furthermore, As per reports of Energy Mix, New Zealand’s oil consumption is around 49 million barrels of oil per year and 4.7 billion cubic meters per year of natural gas per year. This is more than 1600 liters of crude oil per person, per year.


New Zealand’s total energy consumption is 589 PJs that come from 60% Non-renewable sources as well as 40% renewable sources. This total energy consumption is 0.15% of the world’s annual consumption. Oil, Gas, Coal, Hydro, Wind, Geothermal, Solar as well as wood all contribute to the total energy consumption in New Zealand. 


Conclusion

Now with all the development in renewable energy sources, the country is still pursuing its target of 95% of electricity generation from renewable energy. Most of this renewable energy is generated via renewable energy companies in New Zealand. The country aims to achieve this number by 2025. To achieve this number the company has been implementing and improving its way of generating renewable energy sources. The country is adding wind farms, finding new biomass, and working on solar as well as Hydro and geothermal.


Likewise, the country wants to build a 100% renewable electricity grid. Therefore, the country has put NZ$30 million into this project. This project is based on investigating pumped hydro storage which uses cheap electricity to pump river or lake water into an artificial reservoir. This is because it can be released to generate electricity when needed, mostly during dry years when hydro lakes are low.


The sheer hard work and efforts of New Zealand are clearly seen. All this is for achieving Net Zero Carbon emissions by 2050. To achieve this, the country’s 60% increment in supply in the next 30 years will mainly come via new wind as well as solar generation and geothermal. But new hydro dams are unlikely to be built because of their significant environmental impacts. 


Let’s hope New Zealand never stops its path of development in renewable energy and continues to grow as time passes by. If the country achieves its aim of net Zero Carbon Emissions then it won’t be just helpful for them but for the world because it will help decrease the effects of climate change. Thus, other countries will also get inspired and race towards the same aim of net Zero Carbon Emissions that will be beneficial for all living creatures of the world.
