Tesla beats earnings forecast in third quarter 2024

Tesla


Tesla shares climbed 12% in extended trading after the company’s third-quarter earnings beat Wall Street estimates, following a long slump.

However, Tesla’s revenue for that period, up 8% year on year, marginally missed expectations. “Vehicle growth” will hit up to 20%-30% next year, said CEO Elon Musk, thanks to “lower cost vehicles” and the “advent of autonomy.” Apparently, this was presented as a ‘best guess’.

Profit margins reportedly received a boost from $739 million in automotive regulatory credit revenue during the quarter. Automakers must acquire a certain number of regulatory credits annually. Those unable to meet the requirement can buy credits from companies like Tesla, which has a surplus due to its exclusive production of electric vehicles.

Automotive revenue reportedly rose 2% to $20 billion, up from $19.63 billion in the same quarter the previous year, and has remained roughly stable since late 2022. Energy generation and storage revenue reportedly surged 52% to $2.38 billion, while services and other revenue, which includes income from non-warranty Tesla vehicle repairs, increased by 29% to $2.79 billion.

Wind power is being wasted adding £40 to household energy bills, according to think tank

Wind turbine and battery

Wasted wind power will add £40 to the average UK household’s electricity bill in 2023, according to a think tank.

That figure could increase to £150 in 2026, Carbon Tracker has estimated.

When it is very windy, the grid cannot handle the extra power generated. So, wind farms are paid to switch off and gas-powered stations are paid to fire up. The cost is passed on to consumers.

The government said major reforms will halve the time it takes to build energy networks to cope with extra wind power. Energy regulator Ofgem announced new rules in November 2023, which it said would speed up grid connections.

Bottleneck

Most of the UK’s offshore wind farms are in England. Dogger Bank, off the coast of Yorkshire is the largest in the world. Meanwhile, around half of onshore wind farms are in Scotland but most electricity is used in south-east England.

Carbon Tracker said the main problem in getting electricity to where it is needed is a bottleneck in transmission.

Wind curtailment

The practice of switching off wind farms and ramping up power stations is known as wind curtailment. This cost is passed on to consumers, it said. Carbon Tracker researches the impact of climate change on financial markets. It said since the start of 2023, wind curtailment payments cost £590m, adding £40 to the average consumer bill.

It warned the costs were set to increase adding £180 per year to bills by 2030. Wind farms are being built faster than the power cabling needed to carry the electricity.

Cable issue

‘The problem is, there are not enough cables. The logical solution would be to build more grid infrastructure,‘ said an analyst at Carbon Tracker. ‘It’s not even that expensive,’ he added, compared with mounting wind curtailment costs.

Industry group RenewableUK reportedly said that grid constraints, ‘reflect a chronic lack of investment in the grid.’

‘We need to move from a grid which is wasteful, to one that’s fit for purpose as fast as possible.’

However, historically it has taken between 10 and 15 years for new transmission cables to be approved.

Maybe more battery storage plants around the UK would help reduce the bottlenecks? As renewable power continues to expand, this would enable the extra power to be stored to use later.

This would be better than firing up antiquated fossil fuel power plants.

Desert location for energy and power generation

Electricity infrastructure

Will these projects alter the world weather pattern?

According to a study, installing large-scale wind and solar farms in the Sahara desert could increase rainfall and vegetation in the region. The researchers simulated the effects of covering 20% of the Sahara with solar panels and wind turbines and found that it would trigger a feedback loop of more monsoon rain and more plant growth.

This could have benefits for the local environment and the global climate, as well as providing a huge amount of clean energy for the world.

Could it also create a detrimental effect to the ecosystem too?

10.5 GW solar energy

The desert project would produce 10.5 GW of solar power and 3 GW of wind power. However, there are also challenges and uncertainties involved, such as the cost, feasibility, and environmental impacts of such a massive undertaking.

The Sahara is a desert on the African continent. With an area of 9,200,000 square kilometres, it is the largest hot desert in the world and the third-largest desert overall, smaller only than the deserts of Antarctica and the northern Arctic.

Daily global electricity energy demand

The global electricity energy demand is the amount of electricity that the world needs in a given day. It can be calculated by multiplying the average global electricity demand in GW by 24 hours. According to the International Energy Agency (IEA), the average global electricity demand in 2020 was about 3 TW or 3 000 GW. This means that the global electricity energy demand in 2020 was about 72 000 GWh or 72 TWh per day. However, this is an average value, and the actual demand may vary depending on the season, time of day, weather, and other factors.

The global electricity energy demand is expected to increase in the future, as population grows and living standards improve. The IEA projects that the average global electricity demand will reach 3.8 TW or 3 800 GW by 2030 and 5.2 TW or 5 200 GW by 2050 in the Announced Pledges Scenario, which reflects the full implementation of net-zero emissions targets by some countries and regions. This implies that the global electricity energy demand will reach 91 200 GWh or 91.2 TWh per day by 2030 and 124 800 GWh or 124.8 TWh per day by 2050.

Energy sources

The sources of electricity generation will also change in the future, as renewable technologies such as solar PV and wind become more dominant and coal use declines. The IEA reports that the main sources of electricity generation in 2020 were coal (34%), natural gas (23%), hydropower (16%), nuclear (10%), wind (8%), solar PV (4%), biofuels and waste (3%), and other renewables (2%).

The researchers simulated the effects of covering 20% of the Sahara with solar panels and wind turbines and found that it would trigger a feedback loop of more monsoon rain and more plant growth.

In the Announced Pledges Scenario, renewables in electricity generation rise from 28% in 2021 to about 50% by 2030 and 80% by 2050.

Powering the UK from energy generated in Morocco

Energy from Xlinks project

The Xlinks Morocco-UK Power Project is a proposal to create a large-scale renewable energy complex in Morocco and feed the electricity to the UK via a long underwater cable.

Key facts

12 million solar panels, 530 wind turbines over 62 square miles.

  • The project aims to produce 10.5 GW of clean power from solar and wind facilities in Morocco’s Guelmim Oued Noun region. This is equivalent to about 10% of the UK’s electricity demand.
  • The project also plans to build a 20 GWh/5 GW battery storage facility to ensure a stable and reliable supply of electricity.
  • The project will use proven high-voltage direct current (HVDC) interconnector technology to transmit the electricity to the UK via a 3,800 km route under the seabed. The cable will connect to two locations in Devon and Wales, each with a capacity of 1.8 GW.
  • The project will create over 11,000 new green jobs in the UK and Morocco, and contribute to their renewable industrial ambitions. It will also diversify the UK’s energy sources and reduce its dependence on EU interconnectors, LNG imports, and biomass from North America.

  • The project is seeking a 25-year contract with the UK government to guarantee a fixed electricity price and secure financing for the £20 billion investment. 
  • It hopes to start construction in 2024 and deliver power to the UK by 2028.

Entirely powered by sun and wind

The Xlinks Morocco-UK Power Project will be a new electricity generation facility entirely powered by solar and wind energy combined with a battery storage facility. Located in Morocco’s renewable energy rich region of Guelmim Oued Noun, it will be connected exclusively to Great Britain via 3,800km HVDC sub-sea cables.

Zero carbon power generation

When domestic renewable energy generation in the United Kingdom drops due to low winds and short periods of sun, the project will harvest the benefits of long hours of sun in Morocco alongside the consistency of its convection Trade Winds, to provide a firm but flexible source of zero-carbon electricity.

UK to issue new oil and gas licences for energy independence

Fossil fuels still needed for energy security

Green?

The UK government has announced a plan to issue over 100 new oil and gas licences in the North Sea, as part of its drive to make Britain more energy independent and reduce reliance on imports. The Prime Minister said that even when the UK reaches net zero by 2050, a quarter of its energy needs will still come from oil and gas.

Carbon Capture

The new licences will be subject to a climate compatibility test and will aim to unlock carbon capture and storage and hydrogen opportunities in the region. The government has also approved two new carbon capture projects in Scotland and the Humber, which are expected to be delivered by 2030.

Criticised

The move has been criticised by environmental groups, who argue that opening up new fossil fuel projects is incompatible with the UK’s climate goals and will undermine its leadership ahead of the COP26 summit in Glasgow. 

They also question the claim that domestic production is cleaner than imports, as the UK’s oil and gas sector is still responsible for significant emissions.

The government has said that it will support the transition of the North Sea industry to low-carbon technologies and protect more than 200,000 jobs in the sector. The UK government has also pledged to invest in renewable energy sources, such as offshore wind, to diversify the UK’s energy mix.
