Exploring the effects of training variables, Bryanton et al. (2012) and Cotter et al. (2013) found that peak knee extensor moments increased with increasing depth (albeit with the same absolute loads).

Enoka (1988) explored hip, knee and ankle joint power outputs in competitive weightlifters during the first pull and transition phases and reported that joint peak power output did not alter with increasing load at the hip, knee or ankle.

Although peak velocity is less well - studied, linear barbell velocity reduces with increasing load (Suchomel et al. 2014a), as do the angular velocities of the hip, knee and ankle joints (Suchomel et al. 2014e).

Exploring the effects of training variables, Kellis et al. (2005) found that joint angles differed between relative loads but did not identify how the individual hip, knee and ankle joints differed; however, List et al. (2013) found that increasing load caused peak ankle angle to become more acute, from no load to 25 % of bodyweight, to 50 % of bodyweight.

Peak force and peak power output increase with increasing load, but RFD does Peak force and peak power output increase with increasing load, but RFD does peak power output increase with increasing load, but RFD does not.

Bryanton et al. (2012) found that peak hip extensor moments increased with increasing depth (albeit with the same absolute loads) but Wretenberg et al. (1996) reported that peak hip extensor moments during both powerlifting squats and during Olympic weightlifting - style squats did not differ substantially between deep and parallel versions (deep = maximal knee flexion vs. parallel = posterior of the hamstrings parallel to the ground).

Increasing load and wearing running shoes rather than no footwear appear to lead to more acute peak knee flexion angles.

Orloff et al. (1997) assessed the effect of load on peak trunk angle and found that there was no effect with increasing load.

Similarly, Wallace et al. (2002) noted that peak knee extensor moment increased between squats with no load to squats with a barbell load equal to 35 % of bodyweight.

Bryanton et al. (2012) reported that peak knee extensor moments did not increase with increasing relative load (data reported but not analysed directly), but Cotter et al. (2013) noted an increase with increasing load.

However, increases in muscle fascicle length are also likely dependent on the mechanical load incurred by the prime mover, as knee flexion (hamstring only) exercise seems to lead to greater adaptations in the hamstrings than hip extension (hamstring, gluteus maximus, and adductor magnus) exercise, even when muscle length at peak contraction is shorter (Bourne et al. 2016).

Increasing load and wearing running shoes rather than no footwear appear to lead to more acute peak knee angles, while using cues to prevent forward knee movement over the toes and fatigue lead to less acute knee angles.

Most other types of external load, including those that add bands and chains to barbells, reduce the size of the peak contraction at long muscle lengths and increase it at shorter muscle lengths.

As expected, mean concentric velocity and peak concentric velocity decreased with increasing relative load (15 — 90 % of 1RM).

Assessing the effect of training variables, Pearson et al. (2009) explored the effect of different relatives loads between 10 % — 100 % and found that mean power output increased to a peak at 50 % of 1RM before reducing to its minimum at 100 % of 1RM.

Comparing the effect of training variables, Clark et al. (2008) found that peak force output increased with greater relative load between 55 % and 80 % of 1RM performed on a smith machine using the Plyobrake system.

Controlling for relative load, the use of accommodating resistance appears to increase both mean and peak bar velocity.

In contrast, Schellenberg et al. (2013) found that peak knee net joint moment during the deadlift did not increase with increasing load (from 25 % to 50 % of bodyweight).

Comparing the effects of different training variables, Swinton et al. (2011a) explored the effects of relative load between 10 — 80 % of 1RM and found that power outputs increased to a peak at 30 % of 1RM for straight bar deadlifts and to a peak at 40 % of 1RM hexagonal bar deadlifts, before reducing to a minimum at 80 % of 1RM.

The issue is particularly sensitive in the fastest - growing nations, with the biggest increase happening in hot countries like India — where the share of AC in peak electricity load could reach 45 % in 2050, up from 10 % today without action.

This is particularly relevant for power systems where the peak load is expected to increase at the same time as conventional power plants to be replaced by intermittent renewable power generation.

Time - of - use Costs: Significant differences between peak and off - peak usage rates or high demand charges mean increasing both solar and battery storage capacity facilitates load - shifting.

Modeling has also shown that it's relatively inexpensive to increase the reliability of the total wind output to a level equivalent to a coal - fired power station by adding a few low - cost peak - load gas turbines that are opearated infrequently, to fill in the gaps when the wind farm production is low (Diesendorf 2010).

«Accordingly, as we concluded in D.P.U. 10 - 54, at 229 - 230, the Cape Wind facility will produce far greater benefits in terms of its: (1) contribution to narrowing the projected gap between supply and demand of renewable resources; (2) contribution to compliance with GWSA emission reductions requirements; (3) contribution to fuel diversity; (4) price suppression effects; (5) ability to act as a hedge against future fuel price increases and volatility; (6) contribution to system reliability; and (7) ability to moderate system peak load.

-- Nothing in this section diminishes any authority of a State or political subdivision of a State to adopt or enforce any law (including regulations) that increases electricity grid efficiency, smart grid and distributed generation deployment, dynamic peak management control, demand response and distributed storage, or the regulation of load - serving entities.

An academic paper last year titled «The Perverse Impact of Calling for Energy Conservation» actually found no peak load reductions — and shoulder increases — in response to mass media calls for conservation.

While the benefit - cost ratio «tends to increase as peak load is reduced, technical limits to the amount the peak load can be reduced with DR and energy efficiency resources limit how much of this benefit can be realized,» the report notes.

The CPUC would be required to increase the percentage of electricity output delivered by clean resources by 5 % in 2020 and by 6 % «every third year thereafter until December 31, 2029, or until 40 % of demand during the peak load time period is supplied by clean peak resources,» the bill reads.

The California Independent System Operator (CAISO)-- the electric system operator for most of the state — will also contend with the normal challenges of managing this complex system including: dry to moderate drought conditions in much of the state, an increasing amount of variable generation from renewable sources, and the challenge of importing about 23 % of its peak system load from sources outside CAISO.
