Want To Limit Global Warming? Electrify Everything, Finds Study | CleanTechnica - 7 views

  • Researchers at the Lappeenranta-Lahti University of Technology (LUT) in Finland and Energy Watch Group (EWG) have completed a 4½ year study that examined how to meet the goals of the Paris climate accords without such measures as carbon capture and geoengineering. Their conclusion? Run everything on electricity and generate all of that electricity using renewables, primarily solar.

    "Thick walls (with 10 inches of insulation, in Bayside Anchor's case) and triple-pane windows keep the building airtight so very little heat escapes. Instead of a central heating system, each apartment has a small electric baseboard heater."

139 Countries Could Transition to 100% Renewable Energy Under New Plan - NBC News - 4 views

  • A team headed by Stanford’s Mark Z. Jacobson outlined plans for 139 nations to transition to 100 percent clean, renewable energy by the year 2050.
  • The shift would also allow the countries to avoid the 3 percent they now spend in their Gross Domestic Products to address the costs of air pollution — mainly in the form of higher health care spending.
  • The plan maps each country and the energy sources it would rely on to reach the 100 percent renewable goal. Water-bound and geologically active Iceland would get 28 percent of its power from hydroelectric sources and nearly 23 percent from geothermal. Parched and wide-open Australia would get nearly 45 percent of its power from wind farms. Poland would get nearly two-thirds of its power from the wind.

  • The paper envisions a world of rapid technological change and a shift in which electricity replaces coal, oil, and gas. Fully implemented, the plans anticipates that 57.6 percent of that electricity would come from solar, 37.1 percent from wind and the rest from a combination of hydroelectric, geothermal, tidal and wave energy.

  • We found that the EV powertrain is $4.6k cheaper to produce than we thought and there is more cost reduction potential left. Consumer cost of ownership (TCO) parity vis-à-vis combustion engine (ICE) cars can be reached from 2018 (first in EU), creating an inflection point for demand.
  • Our detailed analysis of moving and wearing parts has shown that the highly lucrative spare parts business should shrink by ~60% in the end-game of a 100%-EV world, which is decades away.
  • EVs are an opportunity for tech companies because the electronics content in the Bolt is $4k higher than in an ICE car, excluding the battery.
  • ...3 more annotations...
  • Commodities-wise, we detected the highest deviation in weight shares between the Bolt and ICE car in copper, aluminium, battery active materials and rare earths.
  • Highest impact on markets for aluminium, copper, battery active materials, rare earths (all positive) and platinum group metals (negative).
  • Therefore, the cost difference (not the retail price difference) between the Bolt and the VW Golf, which we consider an equivalent ICE car, appears set to shrink to $2.3k.

  • The EU should de-politicise coal by providing a solution to the related socioeconomic issues, such as the difficulties of transition in coal mining regions. T o do so, the EU should broaden the scope and change the functioning of the European Globalisation Adjustment Fund, to make it into a flagship EU initiative that will support European coal miners who will inevitably be affected by EU decarbonisation. By devoting 0.1 percent of its post-2020 budget to this item, the EU could facilitate the elimination of a major stumbling block on its decarbonisation pathway.
  • Box 1: A back-of-the-envelope calculation of the EGCF budget requirements to support the coal phase-out Europeans employed in coal mining = 216,000 (0.07 percent of total) Assuming a 50 percent phase-out between 2020-27 = 108,000 jobs to be phased out (Fair to assume that part of the remaining 50 percent will naturally retire over the period) 108,000 / 7 years = 15,430 jobs to be phased out yearly between 2020-2027 Assuming financial support of €10,000 per worker = €154 million per year Total financial requirement for the coal-item of the EGCF between 2020-27 = €1 billion

  • The transport sector is expected to deliver a 60% reduction in greenhouse gas (GHG) emissions in the EU by 2050. Achieving these commitments is expected to require a complete decarbonisation of the passenger car fleet.

The transition to a Zero Emission Vehicles fleet for cars in the EU by 2050 - 1 views

  • Decarbonising transport is central to achieving Europe’s policy commitments on climate change. T ransport is expected to deliver a 60% greenhouse gas (GHG) emissions reduction target of the EU for 2050. Achieving these commitments is expected to require a complete decarbonisation of the passenger car fleet. The more ambitious COP21 commitment to limit temperature rises to 1.5°C will also likely demand a complete decarbonisation of transport by 2050.
  • Attaining a 100% ZEV fleet by 2050 will require all new car sales to be ZEV by 2035 (assuming a similar vehicle life-time as today) and a substantially faster introduction of ZEVs and PHEVs than current policy and likely 2025 policies will achieve .
  • Compared to the CO2 emission reductions targeted in the current EU plan, the transition to a 100% ZEV car fleet by 2050 will result in an additional reduction of the cumulative CO2 emissions in the period 2020 and 2050 of 2.2 to 3.9 gigatonnes. The current EU White Paper for T ransport, targets to reduce the transport emissions by 60% compared to 1990.

  • The best option for a rapid emission reduction is to focus on BEVs rather than PHEVs whereby the EU goes directly and aggressively to 100% ZEV sales. A scenario where PHEVs are first will push the strong ZEV growth further into the future and will ultimately require a larger effort at a later time. However, the impact of (an early fleet of) PHEVs on reducing ZEV costs, increasing consumer acceptance and promoting investments in charging / fuelling infra is difficult to predict / model and may play an important role as well.
  • The “Tank to Wheel” amount of energy needed for transport will be reduced by 78% compared to today for a transition to a BEV passenger car fleet. A transition to a 100% fuel cell electric vehicle fleet will result in a 46% reduction of energy for the EU’s car fleet.
  • Around 1,740 million barrels of oil per year could be saved by 2050 with the transition to a zero-emission passenger car fleet, the equivalent of € 78 billion at the current price of 45 $ per barrel.
  • The GHGs from oil will potentially get higher if shifting to for example oil sands .
  • Purchase cost parity is assumed to be achieved in the period 2022-2026 for a BEV and a comparable internal combustion engine vehicle (ICEV), with BEVs being comparatively lower in cost after that. Parity at Total Cost of Ownership (TCO) level will be achieved 2 to 4 years before the purchase cost parity is achieved. The average TCO for a ZEV will be €0.04 to €0.06 per kilometre less than an ICEV by 2030.
  • This represents societal savings of € 140 billion to € 210 billion per year for a 100% ZEV EU car fleet.
  • A mass market for ZEV cars will create synergy for the cost competitive development of a ZEV LCV (Light Commercial V ehicles) market representing 17% of the light vehicles emissions. It will also accelerate the development of a HDV (Heavy Duty V ehicle) ZEV / PHEV market for passenger and goods transportation. It will also free up advanced biofuels for other transport sectors.
  • A lithium-ion battery manufacturing capacity of 400 to 600 Gigawatt hours will be required at the point where 100% of the passenger cars in Europe sold will be BEV . This is the equivalent of around 10 to 14 “Giga factories” representing a value of €40 to 60 billion per year for cars alone.
  • In addition, as BEVs have superior driving performance characteristics and people used to driving electric do not return to ICEVs, the transition may become demand driven once the price, range and infrastructure barriers have been removed.
