10% of U.S. Electricity From Solar by 2025 : CleanTechnica - 0 views

  •  
    The Utility Solar Assessment Study produced by Clean Edge and Co-op America finds that solar energy is already reaching cost parity with conventional sources in some areas of the U.S. where electric rates are highest. By 2015, this will be achieved in many more areas, including Boston, San Diego, and New York. By 2025, cost parity will be achieved throughout the U.S.
  •  
    A percentage of someting by sometime somewhere. With about 200 countries, 10 decades (20 if we include the mid decades) and at least 10 mainstream technologies, we can still produce 20,000 of these stories. At one per day, we'll be busy until 2070.

EERE News: Report: Efficiency Could Cut Growth in U.S. Energy Use in Half - 0 views

  • An aggressive pursuit of energy efficiency in the United States over the next 18 years could cut the nation's growth in energy use by 50% or more, according to a new report. The report, "Vision for 2025: Developing a Framework for Change," was prepared by the National Action Plan for Energy Efficiency Leadership Group, which comprises more than 60 leading organizations, with DOE and the U.S. Environmental Protection Agency (EPA) acting as facilitators. The report sets a goal of achieving all cost-effective energy efficiency improvements throughout the United States by 2025. If that goal is achieved, the nation will spend $100 billion less for energy in 2025 than it would otherwise and will avoid emitting 500 million metric tons of carbon dioxide per year. The nation will also achieve $500 billion in net savings from its energy efficiency investments.

American Wind Energy Association: Wind Power Trends to Watch for in 2009 - 0 views

  •  
    New policies include: adjusting the federal production tax credit (PTC) to make it more effective in the midst of the current economic downturn and extending it for a longer term (it expires at the end of 2009); establishing a national renewable electricity standard (RES) with a target of generating at least 25% of the nation's electricity from renewables by 2025, and a near-term target of 10% by 2012 (a Washington Post poll in early December found that 84% of Americans support such a standard); legislation and initiatives to develop a high-voltage interstate transmission "highway" for renewable energy; and strong national climate change legislation.

New Zealand Commits to 90% Renewable Electricity by 2025 - 0 views

  • In a speech this week, New Zealand Prime Minister Helen Clarke announced New Zealand's intention to commit to 90% renewable electricity by 2025, according to a press release issued by the New Zealand government. The country already uses 70% renewable electricity, primarily hydro- and geothermal power and will continue to increase its use of renewables over the next 20 years.

Clean Break :: Enhanced geothermal attracting $$$ in North America - 0 views

  • The way this Icelandic investor sees it, the U.S. has the potential for a six-fold increase in its installed geothermal capacity, which would double existing global capacity. "Glitnir estimates that investments of $9.5 billion (U.S.) are required in projects currently under development, and that further $29.9 billion are needed between now and 2025 to develop and harness future resources,"

Evaluating the Cleanliness of Solar Photovoltaics Can Be Complicated : CleanTechnica - 0 views

  • Take a good look at panels that have been installed for several years and you will notice discontinuities and shiny areas where the components have been damaged and where the power production is reduced.
    • Hans De Keulenaer
       
      There's an idea. Only once I've seen a paper on long-term performance of panels.
  • Though there are no visibly moving parts in a solar PV panel, there are many parts of the system where continuous chemical and physical reactions take place that can eventually lead to system degradation and failure.
    • Hans De Keulenaer
       
      Makes sense. Roofs have no moving parts as well, yet we're always concerned of infiltrations.
  • Leaves and snow are particular nuisances for rooftop solar panels, but sand and bird droppings can be important in some areas as well.
    • Hans De Keulenaer
       
      Few solar advocates are part of the BC sector.

    Solar photovoltaic (PV) cells are a popular and often discussed (see, for example Atlantic City Convention Center Plans Largest Solar Roof in U.S., 10% of U.S. Electricity From Solar by 2025, SF Passes Largest City Solar Program in U.S. (Finally), all of which were published within the past week) form of "renewable" or "green" energy, but a casual scratching of the surface knowledge that many people have about the technology reveals some troubling details.

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

shared by Hans De Keulenaer on 14 Nov 17 - No Cached
  • 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.

Growth of solar energy is not in line with the needs for ambitious energy transition | EU Science Hub - 3 views

  • With an installed capacity of 117 GW at the end of 2018, the EU further lost ground in the worldwide market.
  • According to a recent 100% RES scenario of the Energy Watch Group, the EU needs to increase its PV capacity from 117 GW to over 630 GW by 2025 and 1.94 TW by 2050 in order to cover 100% of its electricity needs by renewable energy.
