concludes
that “starting in 2024,
the rest of this decade
could look
more like
the second half of the 1990s than the second half of the 1970s”.
另一家银行瑞银的杰森·德拉霍的最新研究得出结论，“从 2024 年开始，到2030年这剩下的几年时间可能看起来更像 1990 年代后半期，而不是 1970 年代后半期”。
（背景知识：
70年代中期至70年代末，美国经济发展缓慢，出现停滞现象通货
膨胀；
90年代，美国经济增长稳健、失业率走低、出口强劲

The growth in electric car ownership could strain
power
grids
if most drivers continue charging primarily at home overnight. Investment in daytime charging options will be crucial to help the western US power grid handle the demand with an estimated 50 per cent of drivers using electric vehicles by 2035.
如果大多数司机持续主要在家里充电过夜，电动汽车保有量的增长可能会给电网带来压力。选择投资白天充电设施，对帮助美国西部电网应对这一需求来说至关重要。到2035年，估计有50%的司机选择驾驶电动汽车。
That finding comes from computer models looking at how driver charging behaviours and available charging station infrastructure at home and in public places could impact peak net electricity demand – the highest electrical power demand minus power provided by solar and wind power.
这一发现来自计算机模型，该模型研究了司机的充电行为，以及家中及公共场所可用的充电站基础设施如何对峰值净电力需求造成影响——这个指标是指电力峰值需求减去由太阳能和风能提供的电力。
If drivers primarily charge vehicles at home during the night, that could lead to a 25 per cent surge in peak net electricity demand when states reach 50 per cent electric vehicle ownership, and possibly surpass grid capacity at even higher levels of ownership.
But expanding daytime charging opportunities could reduce that increase in peak net electricity demand to just 7.5 per cent and help reduce the costs of expanding grid capacity.

但增加白天充电的机会，可能将峰值净电力需求的增幅降至7.5%，并有助于降低扩大电网容量的成本。
The findings also show how a shift to daytime charging
patterns
could help the western US grid efficiently use its excess solar power, says Ram Rajagopal at Stanford University. Daytime charging can
tap
solar power when it is immediately available, instead of requiring power grid operators to invest in more energy storage to store daytime solar power for night-time charging.
斯坦福大学的拉姆•拉贾戈帕尔表示，研究结果还表明，转向白天充电模式可能有助于美国西部电网有效利用过剩的太阳能。白天充电可以在太阳能可用时就立即使用它，避免要求电网运营商在能源存储上投入更多资金，来存储白天的太阳能以供夜间充电。
The computer models showed that having more drivers charging during the day could reduce the grid’s energy storage requirements by between $700 million and $1.5 billion, compared with a business-as-usual
scenario
with many drivers charging at home during the night.
计算机模型显示，与通常许多司机晚上在家充电的情况相比，有更多司机在白天充电可以相应减少7亿-15亿美元的电网储能需求。
