Environmental opportunity cost of renewable energy useCarbon capture and utilization (CCU) to produce methanol is a beneficial pathway to use carbon dioxide (CO2) and mitigate climate change. Existing life cycle assessments demonstrate that CCU methanol generates a net CO2 benefit when the hydrogen (...

As expected, rapid decreases in the costs of renewable energy sources lead to the larger installation of wind and solar capacity. By 2030, the low-cost renewables (R) scenario, compared with the BAU scenario, would lead to an increase in wind capacity from 660 to 850 GW and in solar c...
Adding a target for renewable energy to EU climate policy causes excess costs. These excess costs are evaluated using a computable general equilibrium model. Excess turn out to be between zero and 32% of the costs without a target for renewable energy. Crucial model elements are the steepness ...

What is one of the main challenges of renewable energy? A. High cost B. Lack of government support C. Intermittency D. Limited availability 相关知识点: 试题来源: 解析 C。解析:文中提到可再生能源的主要挑战之一是间歇性,太阳能和风能依赖天气条件,水能受降雨和河流流量影响。
Microgrids using renewable energy resources are increasingly in use, and various design techniques to optimize the facility capacity of the microgrid components (photovoltaic power generation and an energy storage system) have been proposed in many papers [1,2,3,4,5,6,7,8,9,10]. In most ...
We describe a mechanism that induces a high indirect cost of renewable energy due to its impact on the heat rate of fossil-fuel power plants. We introduce a compelling instrumental variable to establish the causal effect. The empirical analysis is conducted using the provincial data in China at...
of renewable resources complement one another, hybrid systems increase load factors and reduce maintenance and replacement costs5. In actuality, energy generation from sporadic energy sources may lead to a misalliance between production and demand. Flexible renewable energy generating systems are paired ...
