The utilization of geothermal energy is nothing new. Within the last century, geothermal energy was harnessed by plants to produce energy.

Countries around the world, particularly those bordering and within the Ring of Fire, are weighing their options regarding geothermal energy. As it stands, geothermal energy has the global potential to generate 200 gigawatts of electricity, and the world is tapping into only 5 of it.

The United States and the Philippines lead the world in terms of geothermal development, although potential is underutilized. Nations in the Asia-Pacific region have the largest potential for growth in the geothermal sector, with some 74 GW waiting to be exploited through drilling and power plants. Japan has been slow to develop its potential, mainly due to issues with terrain, aesthetics and seismic activity however, its long dormancy is finally coming to an end.

South Korea is also preparing to boost its geothermal sector after thorough testing estimated that tapping 2 of the country's potential could provide as much energy as an entire year's demand. Australia, with more than 9 GW of regional geothermal potential at its disposal, is also pushing to increase its capacity. It currently does not rank among the top 10 nations capable of geothermal energy production.

Most geothermal development within Australia seems to be taking place after 2012, although a few projects may take off before then. Petratherm Limited plans to develop a small pilot plant near Arkaroola in South Australia starting at the end of next year. If the 3.75-megawatt MW Paralana project proves successful after completion in 2012, the company will immediately scale up the $45 million project to demonstration size before commercializing.

Initially, the new plant will supply power to a nearby uranium mine, though eventually it will be connected to local grid. Other projects are in the works as well, but Australia is in a state of flux as it determines the best routes of development through the utilization of enhanced geothermal systems, such as Paratherm's Paralana project.

Geothermal development became a hot topic in 2008 after the Australian Geothermal Energy Association's AGEA release of a report that suggested energy policies could allow for the development of more than 2 GW of geothermal power by 2020, which would cover up to 40 of the government's renewable energy targets. By then, renewable energy is projected to account for at least 20 of energy demand in Australia.

The AGEA also mentioned that developing only 1 of the region's geothermal potential could provide the country with enough energy to meet demands for more than 20,000 years. These estimates provide hopeful news as Australia depends mainly on coal for power needs and is one of the largest per capita carbon producers in the world.

Trump Tariff Threat Delays Quebec's Green Energy Bill

Quebec Energy Bill Tariff Delay disrupts Canada-U.S. trade, renewable energy investment, hydroelectric expansion, and clean technology projects, as Trump tariffs on aluminum and steel raise costs, threatening climate targets and green infrastructure timelines.

 

Key Points

A policy pause in Quebec from U.S. tariff threats, disrupting clean investment, hydro expansion, and climate targets.

✅ Tariff risk inflates aluminum and steel project costs.

✅ Quebec delays clean energy legislation amid trade uncertainty.

✅ Hydroelectric reliance complicates emissions reduction timelines.

 

The Trump administration's tariff threat has had a significant impact on Quebec's energy sector, with tariff threats boosting support for projects even as the uncertainty resulted in the delay of a critical energy bill. Originally introduced to streamline energy development and tackle climate change, the bill was meant to help transition Quebec towards greener alternatives while fostering economic growth. However, the U.S. threat to impose tariffs on Canadian goods, including energy products, introduced a wave of uncertainty that led to a pause in the bill's legislative process.

Quebec’s energy bill had ambitious goals of transitioning to renewable sources like wind, solar, and hydroelectric power. It sought to support investments in clean technologies and the expansion of the province's clean energy infrastructure, as the U.S. demand for Canadian green power continues to grow across the border. Moreover, it emphasized the reduction of carbon emissions, an important step towards meeting Quebec's climate targets. At its core, the bill aimed to position the province as a leader in green energy development in Canada and globally.

The interruption caused by President Donald Trump's tariff rhetoric has, however, cast a shadow over the legislation. Tariffs, if enacted, would disproportionately affect Canada's energy exports, with electricity exports at risk under growing tensions, particularly in sectors like aluminum and steel, which are integral to energy infrastructure development. These tariffs could increase the cost of energy-related projects, thereby hindering Quebec's ability to achieve its renewable energy goals and reduce carbon emissions in a timely manner.

The tariff threat was seen as a part of the broader trade tensions between the U.S. and Canada, a continuation of the trade war that had escalated under Trump’s presidency. In this context, the Quebec government was forced to reconsider its legislative priorities, with policymakers citing concerns over the potential long-term consequences on the energy industry, as leaders elsewhere threatened to cut U.S.-bound electricity to exert leverage. With the uncertainty around tariffs and trade relations, the government opted to delay the bill until the geopolitical situation stabilized.

This delay underscores the vulnerability of Quebec’s energy agenda to external pressures. While the provincial government had set its sights on an ambitious green energy future, it now faces significant challenges in ensuring that its projects remain economically viable under the cloud of potential tariffs, even as experts warn against curbing Quebec's exports during the dispute. The delay in the energy bill also reflects broader challenges faced by the Canadian energy sector, which is highly integrated with the U.S. market.

The situation is further complicated by the province's reliance on hydroelectric power, a cornerstone of its energy strategy that supplies markets like New York, where tariffs could spike New York energy prices if cross-border flows are disrupted. While hydroelectric power is a clean and renewable source of energy, there are concerns about the environmental impact of large-scale dams, and these concerns have been growing in recent years. The tariff threat may prompt a reevaluation of Quebec’s energy mix and force the government to balance its environmental goals with economic realities.

The potential imposition of tariffs also raises questions about the future of North American energy cooperation. Historically, Canada and the U.S. have enjoyed a symbiotic energy relationship, with significant energy trade flowing across the border. The energy bill in Quebec was designed with the understanding that cross-border energy trade would continue to thrive. The Trump administration's tariff threat, however, casts doubt on this stability, forcing Quebec lawmakers to reconsider how they proceed with energy policy in a more uncertain trade environment.

Looking forward, Quebec's energy sector will likely need to adjust its strategies to account for the possibility of tariffs, while still pushing for a sustainable energy future, especially if Biden outlook for Canada's energy proves more favorable for the sector in the medium term. It may also open the door for deeper discussions about diversification, both in terms of energy sources and trade partnerships, as Quebec seeks to mitigate the impact of external threats. The delay in the energy bill, though unfortunate, may serve as a wake-up call for Canadian lawmakers to rethink how they balance environmental goals with global trade realities.

Ultimately, the Trump tariff threat highlights the delicate balance between regional energy ambitions and international trade dynamics. For Quebec, the delay in the energy bill could prove to be a pivotal moment in shaping the future of its energy policy.

Africa must quadruple power investment to supply electricity for all, IEA says

Africa Energy Investment must quadruple, says IEA, to deliver electricity access via grids, mini-grids, and stand-alone solar PV, wind, hydropower, natural gas, and geothermal, targeting $120 billion annually and 2.5% of GDP.

 

Key Points

Africa Energy Investment funds reliable, low-carbon electricity via grids, mini-grids, and renewables.

✅ Requires about $120B per year, or 2.5% of GDP

✅ Mix: grids, mini-grids, stand-alone solar PV and wind

✅ Targets reliability, economic growth, and electricity access

 

African countries will need to quadruple their rate of investment in their power sectors for the next two decades to bring reliable electricity to all Africans, as outlined in the IEA’s path to universal access analysis, an International Energy Agency (IEA) study published on Friday said.

If African countries continue on their policy trajectories, 530 million Africans will still lack electricity in 2030, the IEA report said. It said bringing reliable electricity to all Africans would require annual investment of around $120 billion and a global push for clean, affordable power to mobilize solutions.

“We’re talking about 2.5% of GDP that should go into the power sector,” Laura Cozzi, the IEA’s Chief Energy Modeller, told journalists ahead of the report’s launch. “India’s done it over the past 20 years. China has done it, with solar PV growth outpacing any other fuel, too. So it’s something that is doable.”

Taking advantage of technological advances and optimizing natural resources, as highlighted in a renewables roadmap, could help Africa’s economy grow four-fold by 2040 while requiring just 50% more energy, the agency said.

Africa’s population is currently growing at more than twice the global average rate. By 2040, it will be home to more than 2 billion people. Its cities are forecast to expand by 580 million people, a historically unprecedented pace of urbanization.

While that growth will lead to economic expansion, it will pile pressure on power sectors that have already failed to keep up with demand, with the sub-Saharan electricity challenge intensifying across the region. Nearly half of Africans - around 600 million people - do not have access to electricity. Last year, Africa accounted for nearly 70% of the global population lacking power, a proportion that has almost doubled since 2000, the IEA found.

Some 80% of companies in sub-Saharan Africa suffered frequent power disruptions in 2018, leading to financial losses that curbed economic growth.

The IEA recommended changing how power is distributed, with mini-grids and stand-alone systems like household solar playing a larger role in complementing traditional grids as targeted efforts to accelerate access funding gain momentum.

According to IEA Executive Director Fatih Birol, with the right government policies and energy strategies, Africa has an opportunity to pursue a less carbon-intensive development path than other regions.

“To achieve this, it has to take advantage of the huge potential that solar, wind, hydropower, natural gas and energy efficiency offer,” he said.

Despite possessing the world’s greatest solar potential, Africa boasts just 5 gigawatts of solar photovoltaics (PV), or less than 1% of global installed capacity, a slow green transition that underscores the scale of the challenge, the report stated.

To meet demand, African nations should add nearly 15 gigawatts of PV each year through 2040. Wind power should also expand rapidly, particularly in Ethiopia, Kenya, Senegal and South Africa. And Kenya should develop its geothermal resources.

Hydro-Québec to Invest $750 Million in Carillon Generating Station

Hydro-Québec Carillon Refurbishment delivers a $750M hydropower modernization, replacing six turbines and upgrading civil works, water passageways, and grid equipment to extend run-of-river, renewable energy output for peak demand near Montréal.

 

Key Points

A $750M project replacing six units and upgrading civil, water and electrical systems to supply power for 50 years.

✅ Replaces six generating units with Andritz turbines.

✅ Upgrades civil works, water passageways, and electrical gear.

✅ Extends run-of-river output for 50 years; boosts peak supply.

 

Hydro-Québec will invest $750 million to refurbish its Carillon generating station with a major powerhouse upgrade that will mainly replace six generating units. The investment also covers the cost of civil engineering work, including making adjustments to water passageways, upgrading electrical equipment and replacing the station roof. Work will start in 2021, aligning with Hydro-Québec's capacity expansion plans for 2021, and continue until 2027.

Carillon generating station is a run-of-river power plant consisting of 14 generating units with a total installed capacity of 753 MW. Built in the early 1960s, it is a key part of Hydro-Québec's hydroelectric generating fleet, which includes the La Romaine complex as well. The station is close to the greater Montréal area and feeds power into the grid to support industrial demand growth during peak consumption periods.

The selected supplier, turbine manufacturer Andritz, has been asked to maximize the project's economic spinoffs in Québec, as Canada continues investing in new turbines across the country to modernize assets. Once the work is completed, the new generating units will be able to provide clean, renewable energy, supporting Hydro-Québec's strategy to reduce fossil fuel reliance for the next 50 years.

"Carillon generating station is a symbol of our hydroelectric development and plays a strategic role in our production fleet. However, most of the generating units' main components date back to the station's original construction from 1959 to 1962. Hydropower generating stations have long service lives - with this refurbishment, Carillon will be producing clean renewable energy for decades to come." said David Murray, Chief Innovation Officer and President, Hydro-Québec Production.

"In light of today's economic situation, this is an important announcement that clearly reaffirms Hydro-Québec's role in relaunching Québec's economy and strengthening interprovincial electricity partnerships that open new markets. Over 600,000 hours of work will be required for everything from the engineering work to component assembly, creating many new high-quality skilled jobs for Québec industries."

German renewables deliver more electricity than coal and nuclear power for the first time

Germany renewable energy milestone 2019 saw wind, solar, hydropower, and biomass outproduce coal and nuclear, as low gas prices and high CO2 costs under the EU ETS reshaped the electricity mix, per Fraunhofer ISE.

 

Key Points

It marks H1 2019 when renewables supplied 47.3% of Germany's electricity, surpassing coal and nuclear.

✅ Driven by high CO2 prices and cheap natural gas

✅ Wind and solar output rose; coal generation declined sharply

✅ Flexible gas plants outcompeted inflexible coal units

 

In Lippendorf, Saxony, the energy supplier EnBW is temporarily taking part of a coal-fired power plant offline. Not because someone ordered it — it simply wasn't paying off. Gas prices are low, CO2 prices are high, and with many hours of sunshine and wind, renewable methods are producing a great deal of electricity as part of Germany's energy transition now reshaping operations. And in the first half of the year there was plenty of sun and wind.

The result was a six-month period in which renewable energy sources, a trend echoed by the EU wind and solar record across the bloc, produced more electricity than coal and nuclear power plants together. For the first time 47.3% of the electricity consumers used came from renewable sources, while 43.4% came from coal-fired and nuclear power plants.

In addition to solar and wind power, renewable sources also include hydropower and biomass. Gas supplied 9.3%, reflecting how renewables are crowding out gas across European power markets, while the remaining 0.4% came from other sources, such as oil, according to figures published by the Fraunhofer Institute for Solar Energy Systems in July.

Fabian Hein from the think tank Agora Energiewende stresses that the situation is only a snapshot in time, with grid expansion woes still shaping outcomes. For example, the first half of 2019 was particularly windy and wind power production rose by around 20% compared to the first half of 2018.

Electricity production from solar panels rose by 6%, natural gas by 10%, while the share of nuclear power in German electricity consumption has remained virtually unchanged despite a nuclear option debate in climate policy.

Coal, on the other hand, declined. Black coal energy production fell by 30% compared to the first half of 2018, lignite fell by 20%. Some coal-fired power plants were even taken off the grid, even as coal still provides about a third of Germany's electricity. It is difficult to say whether this was an effect of the current market situation or whether this is simply part of long-term planning, says Hein.

 

Activists storm German mine in anti-coal protest

It is clear, however, that an increased CO2 price has made the ongoing generation of electricity from coal more expensive. Gas-fired power plants also emit CO2, but less than coal-fired power plants. They are also more efficient and that's why gas-fired power plants are not so strongly affected by the CO2 price

The price is determined at a European level and covers power plants and energy intensive industries in Europe. Other areas, such as heating or transport are not covered by the CO2 price scheme. Since a reform of CO2 emissions trading in 2017, the price has risen sharply. Whereas in September 2016 it was just over €5 ($5.6), by the end of June 2019 it had climbed to over €26.

 

Ups and downs

Gas as a raw material is generally more expensive than coal. But coal-fired power plants are more expensive to build. This is why operators want to run them continuously. In times of high demand, and therefore high prices, gas-fired power plants are generally started up, as seen when European power demand hit records during recent heatwaves, since it is worth it at these times.

Gas-fired power plants can be flexibly ramped up and down. Coal-fired power plants take 11 hours or longer to get going. That's why they can't be switched on quickly for short periods when prices are high, like gas-fired power plants. In the first half of the year, however, coal-fired power plants were also ramped up and down more often because it was not always worthwhile to let the power plant run around the clock.

Because gas prices were particularly low in the first half of 2019, some gas-fired power plants were more profitable than coal-fired plants. On June 29, 2019, the gas price at the Dutch trading point TTF was around €10 per megawatt hour. A year earlier, it had been almost €20. This is partly due to the relatively mild winter, as there is still a lot of gas in reserve, confirmed a spokesman for the Federal Association of the Energy and Water Industries (BDEW). There are also several new export terminals for liquefied natural gas. Additionally, weaker growth and trade wars are slowing demand for gas. A lot of gas comes to Europe, where prices are still comparatively high, reported the Handelsblatt newspaper.

The increase in wind and solar power and the decline in nuclear power have also reduced CO2 emissions. In the first half of 2019, electricity generation emitted around 15% less CO2 than in the same period last year, reported BDEW. However, the association demands that the further expansion of renewable energies should not be hampered. The target of 65% renewable energy can only be achieved if the further expansion of renewable energy sources is accelerated.

BC Hydro completes major milestone on Site C transmission line work

Site C 500 kV transmission lines strengthen the BC Hydro grid, linking the new substation and Peace Canyon via a 75 kilometre right-of-way to deliver clean energy, with 400 towers built and both circuits energized.

 

Key Points

High-voltage lines connecting Site C substation to the BC Hydro grid, delivering clean energy via Peace Canyon.

✅ Two 75 km circuits between Site C and Peace Canyon

✅ Connect new 500 kV substation to BC Hydro grid

✅ Over 400 towers built along existing right-of-way

 

The second and final 500 kilovolt, 75 kilometre transmission line on the Site C project, which has faced stability questions in recent years, has been completed and energized.

With this milestone, the work to connect the new Site C substation to the BC Hydro grid, amid treaty rights litigation that has at times shaped schedules, is complete. Once the Site C project begins generating electricity, much like when the Maritime Link first power flowed between Newfoundland and Nova Scotia, the transmission lines will help deliver clean energy to the rest of the province.

The two 75 kilometre transmission lines run along an existing right-of-way between Site C and the Peace Canyon generating station, a route that has seen community concerns from some northerners. The project’s first 500 kilovolt, 75 kilometre transmission line – along with the Site C substation – were both completed and energized in the fall of 2020.

BC Hydro awarded the Site C transmission line construction contract to Allteck Line Contractors Inc. (now Allteck Limited Partnership) in 2018. Since construction started on this part of the project in summer 2018, crews have built more than 400 towers and strung lines, even as other interties like the Manitoba-Minnesota line have faced scheduling uncertainty, over a total of 150 kilometres.

The two transmission lines are a major component of the Site C project, comparable to initiatives such as the New England Clean Power Link in scale, which also consists of the new 500 kilovolt substation and expanding the existing Peace Canyon 500 kilovolt gas-insulated switchgear to incorporate the two new 500 kilovolt transmission line terminals.

Work to complete three other 500 kilovolt transmission lines that will span one kilometre between the Site C generating station and Site C substation, similar to milestones on the Maritime Link project, is still underway. This work is expected to be complete in 2023.
