Bendexan bigarkiyan wind turbines û hydroelectric power (hydropower plants) ji solar panels re bikar bînin ji bo bendexanên mezburan yekê, pir hemîn jî dihewin da ku li ser çewtiya cihêr, bêtirina wan, cost-effectiveness, û pirtûkê teknolojî de ne.

Stability energy

Wind turbines û hydropower zêdetir stabîl ne

• Wind turbines: Ewger dîja wind speed dikeve wekheviyek, lê li ser derbarê her dema xwe yên wata, bi management cluster ê yên fansên hêzdar û means weather forecasting, hûn dikarin power output yekê divê bibin êk stabîl rastî. Mînak, li ser kêmkirina wind farms mezin, power output of the whole wind farm dikare be stabîl û fluctuations mezin dikare weraz bike bi rastîn position fans û adopting advanced monitoring and control systems.

• Hydropower: High stability û predictability. Water flow of the river zêdetir stabîl ne û water level change law, bi regulation reservoir, power generation dikare be adjusted according to the demand for electricity. Mînak, large hydropower stations dikarin achieve precise control of power output bi adjusting the storage û release of water in reservoirs to meet the demand for electricity at different times.

Li gorî, solar panel power generation zêdetir têne afetandin ji weather û day û night variations. Intensity of sunlight dikare be guherandin ji clouds, seasons, geographical location û other factors, û it can not generate electricity at night, resulting in unstable output power, difficult to meet the needs of large-scale stable power supply.

Adaptability to the power grid

Wind turbines û hydroelectric power dikarin be better adapted to the needs of the grid. Ji ber ku output power yakan êk stabîl e, it is easier to match the dispatching û operation requirements of the power grid. Mînak, during the peak load of the grid, hydropower station dikare be rapidly increase the generation of electricity to meet the demand for electricity; When the load is low, power generation can be reduced to avoid the overload of the grid.

The intermittency û instability of solar power generation bring great challenges to the dispatching of power grid. The grid needs to be equipped with more energy storage equipment û backup power to cope with fluctuations in solar power generation, increasing the construction û operating costs of the grid.

Cost-benefit aspect

Initial investment û operating costs

Wind turbines û hydroelectric power have certain cost advantages when applied on a large scale. Although initial construction investment of wind turbines û hydroelectric power stations is high, their operating costs are relatively low. Once built, wind û water resources are free, with only maintenance û management of the equipment required. Mînak, large wind farms û hydroelectric power stations have long service lives û can continue to generate electricity for decades at relatively low cost spread over time.

Initial investment cost of solar panels is also high, û with continuous progress of technology, although its price is gradually declining, it still requires larger installation area û supporting equipment. In addition, efficiency of solar panels decreases over time û requires regular replacement, increasing operating costs.

Scale effect

Wind turbines û hydropower are easier to achieve economies of scale. Large wind farms û hydroelectric power stations can generate large amounts of electricity to meet large-scale electricity demand. As scale increases, unit costs can be further reduced. Mînak, some large hydroelectric power stations can have an installed capacity of millions of kilowatts or more, capable of providing a stable power supply to an entire region û country.

When solar panels are used on a large scale, they are limited by installation area û site. Although it is possible to generate electricity in different locations through distributed installation, overall, scale of individual solar power systems is relatively small, û it is difficult to achieve same scale effects as large wind û hydropower plants.

Environmental adaptability

Land use efficiency

Wind turbines û hydroelectric power stations have certain advantages in land use. Wind turbines can usually be installed in open plains, mountains û at sea, occupy a relatively small land area, û can be combined with other industries such as agriculture û animal husbandry to improve land use efficiency. Mînak, in some grassland areas, wind turbines can coexist with livestock farming without affecting normal use of the land.

Although hydroelectric power station needs to build reservoirs, it can improve comprehensive utilization value of land û water resources through comprehensive utilization of reservoir resources, such as development of fisheries û water tourism.

Solar panels require a large installation site, usually on a roof û open ground. In large-scale application, it may occupy a lot of land resources, û produce certain restrictions on use of land.

Environmental impact

Wind turbines û hydropower have relatively little impact on environment. Wind power is a clean energy source that produces no pollutant emissions û has less impact on air quality û climate change. Although wind turbines will produce a certain amount of noise during operation, it can be controlled through reasonable location û technical means.

Although hydropower generation will have a certain impact on river ecosystem, environmental impact can be minimized by adopting measures such as ecological flow guarantee û fish migration channel construction.

Production process of solar panels will consume a lot of energy û resources, û produce certain pollutant emissions. In addition, disposal of solar panels will also cause a certain pressure on environment.
