“…Emissions that arise from the consumption of fuels used in domestic heating and cooling are of special concern, and those can be mitigated by renewables like solar, wind and geothermal. The success of shallow geothermal energy (SGE) as a carbon neutral energy source is especially marked in the Canary Islands 27 . Many cities around the world are in search of SGE 28 to reduce the use of fossil fuels and increase energy efficiency.…”

The city of La Laguna is one of the largest urban areas of the Canary Islands archipelago, located on the volcanic island of Tenerife (Spain), whose energy demand results in a large carbon footprint due to the typical fossil fuel dependency of oceanic islands. In 2019, La Laguna joined the initiative under the new Climate and Energy Pact and has been working ever since to achieve the EU target of reducing by 55% greenhouse gases emissions by 2030. In this work, we present the results obtained from the study conducted of emissions of the city, focused on buildings, equipment and facilities (1), public lighting (2), transportation (3) and agriculture, forestry and fishing (4) sectors. To this end, emissions in 2009 were studied and compared with those in 2019, resulting in a 4% to 48% carbon dioxide emissions reduction in the last decade. To achieve the goal of reductions of more than 55% by 2030, the city council prepared a Sustainable Energy and Climate Action Plan (SECAP), in which they propose that successfully implemented measures would achieve a 64% reduction in emissions in the municipality.

“…Therefore, the more rational use of new energy has become a new heated discussion all around the world. In particular, natural gas, as the world's only fossil clean energy, with its rich reserves, is getting the attention of many governments and scholars [11], so the research of coupling the relationship between natural gas and electricity is of great significance [12]. By studying the shortcomings of traditional energy scheduling and electricity-gas energy scheduling mechanism, an integrated electricity-gas energy optimization system is established based on EH, and the system is tested through circuit principle and hydrodynamics analysis.…”

The electricity-gas transformation problem and related intrinsic mechanisms are considered. First, existing schemes for the optimization of electricity-gas integrated energy systems are analyzed through consideration of the relevant literature, and an Electricity Hub (EH) for electricity-gas coupling is proposed. Then, the distribution mechanism in the circuit of the considered electricity-gas integrated system is analyzed. Afterward, a mathematical model for the natural gas pipeline is elaborated according to the power relationship, a node power flow calculation method, and security requirements. Next, the coupling relationship between them is implemented, and dedicated simulations are carried out. Through experimental data, it is found that after 79 data iterations, the optimization results of power generation and gas purchase cost in the new system converge to $54,936 in total, which is consistent with the data obtained by an existing centralized optimization scheme. However, the new proposed optimization scheme is found to be more flexible and convenient.

“…In this connection, installations based on the method of evaporative air cooling are used [1][2][3]. However, operating experience in production conditions showed that they provide a decrease in air temperature by 6...8 ° C, which is not enough for southern regions with a hot climate, where a cooling depth of 10...15 °C is required [1][2][3][4].…”

The article considers the calculation of the main design parameters of a geothermal air cooling system in livestock premises, which, unlike traditional systems, do not use fossil fuels to generate heat. They simply take energy from the soil, while, as a rule, electricity is used only for the operation of fans, compressors and pumps. The purpose of the study is to reduce energy consumption when creating the technologically necessary temperature and humidity conditions in premises by using the cold of the earth’s strata. The calculation of the heat exchanger installed inside the livestock premises is reduced to the choice of design and energy parameters of the surface heat exchanger of the cooling unit, as well as to the determination of the flow rate of water passing through the heat exchanger. Water cooling is done in a heat exchanger buried vertically in the soil (the so-called probe). The probe is a plastic pipe lowered into the well and filled with a special filling with good thermal conductivity. The article presents the calculation of the probe length, since this parameter of the heat exchanger-probe is the main parameter of the installation.
