<제2세부연구과제 : 주요 시설원예 작물의 화석에너지 및 보온형태별 경영실태 분석 >
농촌진흥청 ‘농산물표준소득조사’ 원자료를 이용하여 주요 시설원예작물의 에너지 이용실태를 분석하였는데 분석대상 년도는 2008년부터 2012년까지이며 대상작물은 오이, 토마토(방울토마토, 일반토마토), 단고추(피망 및 착색단고추), 시설고추, 시설감귤, 시설포도, 시설화훼(시설장미, 시설 심비디움)이다.
작물별 에너지 사용량을 살펴보면, 전반적으로 전기와 석유류를 혼합하여 많이 사용하고 있는 것으로 나타났다. 과일류인 시설감귤과 시설포도 보다는 화훼류인 시설 장미와 심비디움의 에너지 사용량이 많았다. 착색단고추의 경우 중유의 사용금액이 전체 에너지 사용금액의 28.9%를 사용하고 있어 중유도 착색단고추의 가온 에너지원으로 사용되고 있는 것을 알 수있다. 전기는 분석대상 작물 모두에서 전체에너지 사용금액의 10% 내외로 사용되며 여타 에너지원의 사용량은 미미한 수준으로 나타났다. 시설감귤 농가는 석유류 가운데 중유 사용량이 10a당 평균 9,715ℓ로 가장 많았고, 다음으로는 경유 1,955ℓ로 나타났음. 전기는 10a당 평균3,145㎾를 이용하는 것으로 계측돠었다. 시설포도 농가는 석유류 중 경유를 가장 많이 사용하는 것으로 나타났으며, 10a당 평균 2,033ℓ를 사용하였다. 전기사용량은 평균 3,602㎾이었으며 시설화훼농가 또한 전기와 경유 중심의 에너지 사용량을 보이고 있었다. 시설장미의 경우 10a당 평균 44,535㎾를, 시설심비디움의 경우 74,573㎾를 사용하는 것으로 계측되었다.
한편, 시설원예작물에 대한 에너지 요소수요함수를 추정함으로서 에너지 투입요인을 분석한 결과를 정리하면 다음과 같음. 첫째, 작물별로 조건부요소수요함수의 추정치를 볼 경우 오이를 재외한 모든 품목이 일반토마토에 비해 유류수요량이 많은 것으로 추정되었다. 따라서 작물에 따라 유류수요량이 상당히 다르다고 판단할 수 있다. 지역별로 유류수요량이 상당히 차이가 나는데 강원도에 비해 여타 지역의 유류 수요량이 유의미하게 큰 것으로 추정되었다. 시설채소의 유류 요소수요는 자기 가격에 대해 유의미하게 반응하며 반응의 정도는 큰 것으로 추정(자기가 격 탄력성이 1.0 이상)되었다. 또한 여타 생산요소와 대체 및 보완재적 성격을 갖지 않음. 이는 유류가 주로 가온 목적으로 사용되며 이를 여타 생산요소들이 효과적으로 대체 혹은 보완할 수 없기 때문인 것으로 보임. 에너지원별 대체 혹은 보완관계에 대한 연구가 추가될 필요가 있다. 유류 수요량은 작물 품목뿐만 아니라 작기, 작형 및 연도에 따라 크게 다른 것으로 추정되었다. 끝으로 보온덮개의 경우 추정치의 계수가 음으로 추정되어 보온덮개 사용에 따라 유류소비를 줄일 수 있음 알 수있다.
그 다음 시설원예 농가의 경영성과를 살펴보았다. 분석에 이용된 자료는 농산물표준소득 자료 원자료이며, 분석 대상은 농산물표준소득 자료에 포함되어 이용할 수 있는 시설채소, 시설과일, 시설화훼로 구분하였다. 시설채소로는 단고추(착색, 피망), 오이, 일반토마토, 방울토마토, 풋고추를 대상으로 함. 시설과일로는 감귤과 포도, 시설화훼로는 장미와 심비디움을 대상으로하였다. 분석결과, 시설 채소 중 단고추, 오이, 토마토, 풋고추의 에너지 사용금액을 나타내는 광열동력비의 중간재비에서 차지하는 비중은 약 25%에서 40% 수준으로 나타났다. 경영비 대비광열동력비 비중은 10% 후반 대에서 30% 수준인데, 품목별로 중간재대비 광열동력비 비중이 가장 큰 작목은 풋고추로 40.4%를 기록하며 경영비 대비 광열동력비 비중이 가장 큰 작목은 착색단고추로 30.8%이다. 생산량 kg당 광열동력비는 착색단고추가 826원으로 가장 크고 이후풋고추 617원, 방울토마토 458원 순으로 나타났다. 조수입, 부가가치 1,000원당 광열동력비는 착색단고추가 각각 235원, 589원으로 가장 큰 것으로 나타났으며 감귤, 포도, 장미, 심비디움에 대한 에너지 사용금액을 나타내는 중간재비에서의 광열동력비 비중은 약 42%에서 72%수준으로 분석되었다. 분석 작물(감귤, 포도, 장미, 심비디움)중 광열동력비의 중간재비에서 차지하는 비중이 가장 큰 작물은 시설감귤로 72%를 기록하였으며, 광열동력비의 경영비에서도 42%를 기록하여 가장 높게 나타났다. 생산량 kg당 광열동력비는 시설심비디움이 3,582원으로 가장 높게 나왔으며 이후 시설감귤 1,663원, 시설포도 1,194원, 시설장미 78원 순으로 나타났다.
시설채소 농가의 신재생에너지 시설 이용효과에 대한 설문조사에 따르면, 기존 경유 보다 생산 및 난방 효과가 증가한 것으로 나타났으나 품질효과의 경우 기존보다 떨어지는 것으로 나타났다. 또한 기존 경유 시설을 신재생에너지 시설로 교체할 경우 교체비용은 지열히트펌프가 가장 높은 것으로 조사되었다. 신재생에너지 이용 시설에 대해 농민들의 전반적인 인식을 살펴보면 설치비용과 유지 및 보수비용이 비싸다는 의견이 많았으며 반면에 경유를 이용했을 때보다 작물의 수량이나 품질 향상 효과에 대해서는 인색한 평가를 보임을 알 수 있다.
시설채소 농가의 에너지 절감시설 이용효과를 조사한 결과, 농가들이 현재 설치, 운영하고 있는 에너지 절감시설들은 무엇인지 조사한 결과에 따르면, 다온보온커튼이 39.4%로 가장 많았으며, 그 다음 다중피복(28.3%), 수평커튼(17.5%)순으로 나타났다. 에너지 절감시설에 대한 사용후 효과를 비교할 때, 수평커튼이 생산량 증가 및 난방비 절감, 품질향상 효과가 가장 높게 나타남. 반면에 배기열회수 장치의 경우 생산량과 품질향상이 기존에 비해 떨어지는 것으로 나타났다.
시설과일 및 화훼농가를 대상으로 신재생에너지 시설을 도입 농가들의 설문조사에 따르면, 지열히트펌프와 공기열히트펌프의 경우 난방비, 생산량 모두 증가하고, 품질은 좋아지는 것으로 나타났다. 반면, 목재펠릿을 사용하는 농가의 경우, 난방비는 절약되지만 생산량과 품질이 낮아지는 것으로 조사되었다. 한편, 이들 농가들의 에너지 절감시설 이용효과를 분석한 결과, 난방비와 생산량, 품질변화를 살펴보면, 다겹보온커튼과 수평커튼의 효과가 양호하다고 평가되었다. 에너지 절감시설 설치비용 수준은 전반적으로 높은 것으로 나타나며, 특히 다겹보온커튼 과 배기열회수장치, 다중피복의 설치비용이 상당히 높은 것으로 조사되었다

Horticulture farmers in heating costs as part accounts for a large share in farm income and is always part of which has been annoying you are interested, a lot of effort to improve this area were recently the heating using renewable energy an attempt to reduce heating costs through ongoing in several parts.
The use of renewable energy is to convert the existing fossil fuel or sunlight, water, geothermal energy used to convert renewable energy, including biological organisms, the future energy sources for a sustainable energy supply system with the characteristics. Renewable energy has been increases in importance as a regulatory response or loss of insecurity and climate change agreement. In Korea, eight areas of renewable energy (solar, photovoltaic, biomass, wind, small hydro, geothermal, ocean energy, waste-to-energy), and three areas of new energy (fuel cells, coal liquefaction, gasification, hydrogen energy), total There are 11 designated areas of renewable energy no international standards set by the New Energy and waste, according to the standards of the International Energy Agency (IEA), according to the International Energy Agency (IEA) estimates a situation that is not recognized as a renewable energy 2012F OECD average proportion of the national renewable energy (including energy and non-renewable waste playback) showed 30.85%. Korea has recorded the lowest among OECD countries with Israel represented a 0.4% to 1.4%. In Korea, with the exception of waste is not recognized by the IEA drops to 0.7%.
This study investigated the heating costs used in agriculture, will compare the case of using renewable energy and conventional fossil. This finding ways to reduce the heating costs in agriculture through it is an object of the present research.
Economic analysis according to the type of radiator findings, in fruits and vegetables and floriculure farms farmers the difference was slightly higher heating costs.
The average heating costs per 10a of farmers to use the existing radiators in the general homestead farm of fruits and vegetables were accounted for 33.62% of the total operating costs to 9,466,940 won and heating costs for farmers that use renewable energy (wood pellets) Radiators is a 7,516,340 won accounting for 28.52% of the total operating costs to be 1.9506 million was investigated causes a reduction of 5.1%, the average heating costs per 10 farmers to use the existing radiators inexcellent farmers of fruits and vegetables farmers were accounted for 31.51% of the total operating costs to 8,409,700 won, Heating costs for farmers who use renewable energy (wood pellets) Radiators are accounted for 23.03% of the total operating costs to be 2.93998 million was investigated by 5,469,720 won, 8.48% causes a reduction.
Floriculure farms average heating costs per 10a of farmers to use the existing radiators in the general homestead of the farm operating costs were accounted for 35.27% of the total in 10,940,410 won, renewable energy (wood pellets) heating costs for farmers is to use a heater to 8,868,210 won accounting for 30.63% of the total operating expenses were 4.63% cause investigations to be 2,072,200 won savings, the average heating costs per 10a of farmers to use the existing radiators in excellent farm of floriculure farms farmers were accounted for 33.32% of the total operating costs to 9,838,190 won, renewable energy (wood pellets) heating costs for farmers to use the radiators are accounted for 28.96% of the total operating costs to be 1,811,580 won was investigated by 8,026,610 won 4.36% causes a reduction.
If you organize your heating bill savings (per 10a), woke renewable energy in general farmers (wood pellet) heating costs are represented by 8,192,275 won (29.58%), the existing heating costs is 10203675 (34.45%) indicated by a circle 2,038,400 won (4.87% ) was analyzed to be the reduction.
In addition, when renewable energy in excellent farmhouse (wood pellets), when used as a heater 6748165 causes 26% would use the existing radiators 2,375,780 won more 9,123,945 won causes were analyzed to be 32.42% 6.42% reduction.
In a typical farm fruits and vegetables are more floriculure farms renewable energy (wood pellets) is used for heating radiators savings of (10a sugar) is 2.11% lower 1,351,670 won was more, in the case of fruits and vegetables are good farmers than floriculure farms renewable energy (wood pellets) using heaters heating costs savings (per 10a) is 5.93% lower than 2,556,890 won appeared in fruits and vegetables, best farmers in the comparison between the floriculure farms and the operating cost savings through higher heating costs savings based on the technology of fruit and vegetable seeds than regular farms and renewable energy than floriculure farms (wood pellet) heating efficiency is likely higher.
82% of the parts for the increase in heating costs borne by the question about the urgent requirements for improving farm management replied that the most urgent. The next was renovated farmhouse and operating funding is one answer for this urgent investigation of the aging facilities at 66% and 70%, respectively, which is a psychological instability of farmers with the increase of oil price fluctuations in the prices of raw materials and wood pellets according to this analysis was that the effect of.
Questions about the farmers countermeasures in accordance with the rise in oil prices and try to control the timing of the transition appeared to be little or no crop is replacing the heating facilities and thermal insulation and repair of facilities that were 78% and as high as 84%. Heating facilities is relatively stable about the conventional fuel and farm the price you want to replace it with a heating facility with affordable electricity was investigated by the majority.
Heating plant installation and the response that meets in a comprehensive satisfaction survey on the use of 20%, 56% unsatisfied response to the dissatisfaction of 36% of the 18 people had had more complaints about the A/S Looking at the details dissatisfaction details was highest complaints about the facility investment accounted for the second time. A/S portion was mainly talking about the defects in the product itself, not the heating problems in a timely manner difficult to get the necessary repairs are heated when the problem occurs if the product was caused crop damage clothing. In this regard, a solution was proposed in the improvements of.
The satisfaction survey about the installation and use of thermal facilities were generally satisfied with this opinion seureopdaneun. In particular, vinyl, non-woven fabrics, aluminum, and Multi-layer insulation with various insulation in multiple layers such as poly cotton, etc. were the most commonly used and analyzed to the highest satisfaction.
Difficulties in product prices as raw material for wood pellet had a lot to say to the other comments.
By analyzing the economics of renewable energy (wood pellets) Radiators horticulture farmers in this study was to improve the problems of heating thinking most sensitive. If in the case of wood pellet heating efficiency, it is clear this problem occurs, the problem with heating the raw material supply of the product itself superior heating equipment imeneun certainly one improvement compared to conventional heating systems such as policy and complementary part to promote the dissemination and horticulture Bring your heating bill savings of farmers is considered to be a definite help in improving farm competitiveness.
Finally, this study confirmed Had heat loss and insulation according to the average temperature of the heating cost estimates point, I think it would be a little more precise investigation.
This study aims to analyze heating costs for cultivating horticultural crops (vegetables, fruits, ornamental flowers) which consume a lot of energy, and management of each heating type to find out involved issues and suggest strategies for improvement. Strategy are then suggested to save energy in protected cultivation of crops and for disseminating energy saving facilities.
An analysis was made of energy consumed for major crops cultivated in protected facilities by using the original data of ‘Standard Investigation of Agricultural Income’. This analysis shows energy consumed for each crop is generally electricity in combination with oil. More energy is consumed for cultivating ornamental flowers, for example, roses and cymbidiums than fruits, for example, mandarin oranges and grapes, in protected cultivation.
An analysis was made of the energy input factors by estimating a factor demand function for protected cultivation of horticultural crops. The estimate of conditional factor demand function from the analysis is that all crops but cucumber have more demands for oil than ordinary tomatoes. Therefore, demands for oil greatly vary from crop to crop. The demands for oil are estimated to depend on cultivation periods, cultivation types and years of cultivation as well as crops.
Management of farmers who practice protected cultivation (protected cultivation farmers) of crops is that the ratio of heat and power cost which is the amount of consumed energy to intermediate material costs is approximately 25% to 40% for sweet chillies, cucumber, tomatoes, and green chillies, which belong to the category of vegetables by protected cultivation. The ratio of heat and power costs to management costs is analyzed about 10% to about 30%. The crop with the greatest ratio of the heat and power costs to the intermediate material costs is green chillies of 40.4%. The crop of the greatest ratio of heat and power costs to the management costs is colored sweet chillies of 30.8%.
The questionnaire for protected cultivation farmers about the effect of using renewable energy facilities reveals it is more effective for production and heating than using light oil, but exhibits lower quality than using light oil. The highest cost for removing conventional light oil facilities and then installing renewable energy facilities is for installing geothermal heat pumps.
The investigation on the effect of using energy saving facilities by protected cultivation farmer reveals the horizontal curtains are the best in terms of increased production, heating cost saving and quality improvement. On the contrary, the exhaust heat recovery device shows it is not as good as conventional devices in production and quality improvement.
The questionnaire for protected cultivation farmers who cultivate fruits and ornamental flowers and have renewable energy facilities reveals the following. The geothermal heat pumps and the air heat pumps increase both heating costs and production, and contribute to better quality. However, farmers who use wood pellets saved heating costs, but experience lower production and quality.
