Renewable energy sources and other energy technologies as a measure for mitigating the impact of urban heat islands

Urban heat islands (UHI) represent increase of temperature inside cities in regard to their rural environment. Causes formation are diverse and multiple: reduced amount vegetation waterproofing surfaces, changed radiation thermal characteristics materials, urban geometry. Consequences also significant: increasing consumption energy for cooling, negative impact on human health, deterioration air quality. Conventional methods mitigating include reflective green roofs introduction water surfaces cities. Different renewable technologies can have positive islands, but at the same time they contribute greater independency what is goal future development.
