Wind farms (WFs) can affect the local climate, and local climate change may influence underlying vegetation. Some studies have shown that WFs affect certain aspects of the regional climate, such as temperature and rainfall. However, there is still no evidence to demonstrate whether WFs can affect local vegetation growth, a significant part of the overall assessment of WF effects. In this research, based on the moderate-resolution imaging spectroradiometer vegetation index, productivity and other remote-sensing data from 2003 to 2014, the effects of WFs in the Bashang area of Northern China on vegetation growth and productivity in the summer (June–August) were analyzed. The results showed that: (1) WFs had a significant inhibiting effect on vegetation growth, as demonstrated by decreases in the leaf area index, the enhanced vegetation index, and the normalized difference vegetation index of approximately 14.5%, 14.8%, and 8.9%, respectively, in the 2003–2014 summers. There was also an inhibiting effect of 8.9% on summer gross primary production and 4.0% on annual net primary production coupled with WFs; and (2) the major impact factors might be the changes in temperature and soil moisture: WFs suppressed soil moisture and enhanced water stress in the study area. This research provides significant observational evidence that WFs can inhibit the growth and productivity of the underlying vegetation.

Abstract. The Swedish electricity supply system benefits strongly from the natural conditions which allow a high share of hydroelectricity. A complete supply is, however, not possible. Up to now, nuclear power is the other workhorse to serve the country with electricity. Thus, electricity production of Sweden is basically CO₂-free and Sweden has reached an environmental status which others in Europe plan to reach in 2050. Furthermore, there is an efficient exchange within the Nordic countries, Nordpol, which can ease possible capacity problems during dry cold years. In this study we investigate to what extent and with what consequences the base load supply of nuclear power can be replaced by intermittent wind power. Such a scenario leads unavoidably to high wind power installations. It is shown that hydroelectricity cannot completely smooth out the fluctuations of wind power and an additional back-up system using fossil fuel is necessary. From the operational dynamics, this system has to be based on gas. The back-up system cannot be replaced by a storage using surplus electricity from wind power. The surplus is too little. To overcome this, further strong extension of wind power is necessary which leads, however, to a reduction of the use of hydroelectricity if the annual consumption is kept constant. In this case one fossil-free energy form is replaced by another, however, more complex one. A mix of wind power at 22.3GW plus a gas based back-up system with 8.6GW producing together 64.8TWh would replace the present infrastructure with 9GW nuclear power producing 63.8TWh electricity. The specific CO₂-emission increases to the double in this case. Pumped storage for the exclusive supply of Sweden does not seem to be a meaningful investment.

Thank you for meeting with us on Monday to talk about the Moorabool Wind Farm.
We value all feedback received in respect of the project from you, other neighbours to the project and many other members from the broader community. We have reflected on your concerns voiced in the meeting, and have considered how we can best support your intentions to sell your property if the wind farm is built.
As part of this process, we contacted a Ballarat real estate agent to discuss his opinion on the impact of the wind farm on neighbouring property values. The agent we spoke to has 17 years experience selling properties in your area as well as properties around the Waubra wind farm. He is fully aware of the perceived impact the wind farm may have on properties, and he indicated he has no recollection of a wind farm causing a property to be sold below market value. He did indicate that it could potentially take slightly longer for the property to sell depending on the turbine locations relative to the dwellings. We advised the dwelling on the property was greater than one kilometre from a proposed turbine site, and his opinion is there will be little if any impact to the sales process or price. He also indicated rural properties in the Ballan area are in high demand from Melbourne residents looking for a sea change, as well as Geelong and Ballarat residents looking to move closer to Melbourne. We are hopeful that this information can give you some comfort that your property is desirable, in an interesting location, and is likely to be sold at market value. We would be happy to share the agents contact details with you if you would like to discuss this further with him. We also discussed fees associated with the sales and marketing of a rural property, and the services available for consultation to prepare your house for the best possible sales outcome. The agent indicated that $4,000 in marketing fees will register your property on all the major internet sales sites and list advertisements in the local and Melbourne papers. He specified that guidance on improvements required to secure the most lucrative sales price on your house is completed by the real estate agent, and this service is included as part of the 2.2% agency fees. He doesn’t know of any agencies that complete this service in your area and it is standard practice to include this assistance during the consultation process with a real estate agent.
We also discussed in our meeting that a direct financial benefit for wind farm neighbours can be achieved by entry into a voluntary participation agreement. Through this agreement, neighbours, like the host landholders, will receive a direct financial benefit from the wind farm, and in return accept some of the conditions that the host landholders also accept.
In response to your concerns as a neighbour to the wind farm, we are pleased to offer you a participation agreement on the following basic terms.
- A participation payment of $8,000 per year once the wind farm commences, to be made to you (as a neighbour) for the life of the wind farm. These payments will be made annually in advance.
- A once off sign-on payment of $25,000 to help cover the following estimated expenses if you choose to sell your property:
- Removalist fees $10,000
- Contribution to real estate agency fees $10,000
- Marketing fees for property listing $4,000
- Legal fees for participation agreement review $1,000
- Your acceptance of the same amenity standards, which the host landholders for the wind farm have accepted. [See section 4 of the Agreement, below.] The amenity standards agreed with host landholders are in line with the recommendations of the World Health Organisation, and pre-date the planning permit conditions.
- The participation agreement shall be capable of being transferred with the property. It will also be transferred on sale or transfer of ownership of the wind farm. Any transferee will need to be notified and agree to the participation agreement prior to (and as a condition of) sale or transfer. This will ensure that a new owner of the wind farm and any potential buyer of a neighbouring property is informed of the terms of the participation agreement, including the participation payment.
As indicated in the meeting, this agreement does not have ‘gag clauses’ or take away your right to complain about the wind farm. However, you will see in section 4.7 [see below] of the agreement, that the landholder agrees not to object to any development approval or other application or procedure made or initiated by the developer. Given the wind farm already has got a planning permit this clause is probably of little consequence for you. In addition to this clause section 9 [see below] does require the terms of this letter and attached agreement to remain confidential.
4.1(a) The Landholder acknowledges and agrees that the Annual Fee is adequate compensation and consideration for all matters contemplated by this Agreement including (without limitation) any nuisance caused by the construction, use and operation of the Wind Farm.
4.1(b) Without limiting the generality of clause 4.1(a), in consideration of the Annual Fee the Landowner agrees that the Landowner will not:
(i) require the Developer to provide any acoustic suppression or treatment measures in order to minimise any noise impacts resulting from the Wind Farm on the Property or any Dwelling or Permitted Dwelling on the Property (Acoustic Suppression); or
(ii) require the Developer to provide any landscaping treatment to the Property in order to minimise the visual impact of the Wind Farm on the Property or any dwelling on the Property (Landscaping); and
(iii) make any request under the Planning Permit:
(A) for any Acoustic Suppression or attenuation measures; or
(B) for any Landscaping for visual suppression or attenuation measures.
4.3 The Landholder shall not carry out, or allow to be carried out, any development or use of the Property that is likely to unreasonably diminish the security or utility of the Property or the Site for use as part of the Wind Farm. In particular, without the prior written consent of the Developer, the Landholder shall not:
(a) construct any dwelling on the Property additional to the Dwelling and Permitted Dwelling;
(b) erect any device to convert wind energy on the Property, other than a water pumping or other windmill no higher than 25 metres above ground level solely and exclusively for the generation and supply of electricity to the Dwelling, Permitted Dwelling or other buildings and uses on the Property; or
(c) otherwise obstruct or interfere with the potential operation or efficiency of wind turbine generators that form part of the Wind Farm.
4.6 To the extent permitted by law, the Landholder releases the Developer and its Related Persons from any damage, loss, cost, expense or Claim arising from or relating to any impact or effect of the Wind Farm on the Landholder or the Property, including but not limited to impacts or effects created by the construction, use and operation of the Wind Farm.
4.7 The Landholder must not object to any Development Approval or planning or other application or procedure made or initiated by the Developer or any other entity for any use or development of the Site or any neighbouring property that is related to or necessary for the Wind Farm, and must provide all reasonable assistance requested by the Developer for the purposes of obtaining approvals.
9(a) The parties expressly acknowledge that the contents of this agreement (and any documents or information provided by one party to another pursuant to or in connection with this agreement) are confidential and shall not be disclosed to any person except …

Abstract: We conduct a choice-experiment with individuals that recently rented a vacation property along the North Carolina coastline to assess the impacts of a utility-scale wind farm on their rental decisions. Visualizations were presented to survey respondents that varied both the number of turbines and their proximity to shore. Results indicate that there is not a scenario for which respondents would be willing to pay more to rent a home with turbines in view as compared to the baseline view with no turbines in sight. Further, there is a substantial portion of the survey population that would change their vacation destination if wind farms were placed within visual range of the beach. The rental discounts required to attract the segment of the survey population most amenable to viewing wind farms still indicate that rental value losses of five percent or more are possible if a utility-scale wind farm is placed within eight miles of shore.
